The selftest.m4 file is used by gdb, gdbserver and gdbsupport, I think
it belongs in gdbsupport.
gdb/ChangeLog:
* selftest.m4: Move to gdbsupport/.
* acinclude.m4: Update path to selftest.m4.
gdbserver/ChangeLog:
* acinclude.m4: Update path to selftest.m4.
gdbsupport/ChangeLog:
* selftest.m4: Moved from gdb/.
* acinclude.m4: Update path to selftest.m4.

The GDB build in non-development mode (turn development to false in
bfd/development.sh if you want to try) is currently broken:
CXXLD gdb
/home/smarchi/src/binutils-gdb/gdb/disasm-selftests.c:218: error: undefined reference to 'selftests::register_test_foreach_arch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, void (*)(gdbarch*))'

/home/smarchi/src/binutils-gdb/gdbsupport/selftest.cc:96: error: undefined reference to 'selftests::reset()'
This is because the gdbsupport configure script doesn't source
bfd/development.sh to set the development variable. When $development
is unset, GDB_AC_SELFTEST defaults to enabling selftests. I don't think
the macro was written with this intention in mind, it just happens to be
that way.
So gdbsupport thinks selftests are enabled, while gdb thinks they are
disabled. gdbsupport compiles in code that calls selftests:: functions,
which are normally provided by gdb, but gdb doesn't provide them, hence
the undefined references.
Since the macro relies on the `development` variable, I propose to
modify it such that it errors out if $development does not have an
expected value of "true" or "false". This could prevent a future
similar problem from happening while refactoring the configure scripts.
This catches the current problem in the gdbsupport configure script,
which is fixed by sourcing development.sh, as it's done in
gdb/configure.ac and gdbserver/configure.ac.
gdb/ChangeLog:
* selftest.m4 (GDB_AC_SELFTEST): Error out if $development is
not "true" or "false".
* configure: Re-generate.
gdbserver/ChangeLog:
* configure: Re-generate.
gdbsupport/ChangeLog:
* configure.ac: Source bfd/development.sh.
* configure: Re-generate.

While working on the preceding selftests patches, I noticed that some
selftests-specific files are included in the build even when selftests
are disabled, namely disasm-selftest.c and gdbarch-selftests.c. These
files are entirely #if'ed out when building with selftests disabled.
This is not a huge problem, but I think it would make more sense if
these files were simply not built.
With this patch, I propose to put all the selftests-specific source
files into a SELFTESTS_SRCS Makefile variable (even selftest-arch.c,
which is currently added by the configure script).
gdb/ChangeLog:
* Makefile.in (SUBDIR_UNITTESTS_SRCS): Rename to...
(SELFTESTS_SRCS): ... this. Add disasm-selftests.c,
gdbarch-selfselftests.c and selftest-arch.c.
(SUBDIR_UNITTESTS_OBS): Rename to...
(SELFTESTS_OBS): ... this.
(COMMON_SFILES): Remove disasm-selftests.c and
gdbarch-selftests.c.
* configure.ac: Don't add selftest-arch.{c,o} to
CONFIG_{SRCS,OBS}.
* disasm-selftests.c, gdbarch-selftests.c: Remove GDB_SELF_TEST
preprocessor conditions.

The same is done for gdb, gdbserver and gdbsupport. I therefore think
it makes sense to move that to GDB_AC_COMMON.
It is required to move the call to GDB_AC_COMMON so it is before
GDB_AC_SELFTEST in gdbserver/configure.ac, otherwise the $development
variable isn't set when the code behind GDB_AC_SELFTEST executes.
gdb/ChangeLog:
* configure.ac: Don't source bfd/development.sh.
* selftest.m4: Modify comment.
* configure: Re-generate.
gdbserver/ChangeLog:
* configure.ac: Don't source bfd/development.sh, move
GDB_AC_COMMON higher.
* configure: Re-generate.
gdbsupport/ChangeLog:
* configure.ac: Don't source bfd/development.sh.
* common.m4: Source bfd/development.sh.
* configure: Re-generate.

Since I've pushed this other patch:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=3d1e5a43cbe1780ea66df0fe091998ee61177899
I've rebased this series and modified the commit message of patch 1/4, this is
the updated version.

Subject: [PATCH] gdb/selftest.m4: ensure $development is set
Before commit 3d1e5a43cbe ("gdbsupport/configure.ac: source
development.sh"), the GDB build in non-development mode (turn
development to false in bfd/development.sh if you want to try) was
broken because the gdbsupport configure script didn't source
bfd/development.sh to set the development variable.
Since the GDB_AC_SELFTEST macro relies on the `development` variable, I
propose to modify it such that it errors out if $development does not
have an expected value of "true" or "false". This could prevent a
future similar problem from happening while refactoring the configure
scripts. It would have caught the problem fixed by the patch mentioned
earlier.
gdb/ChangeLog:
* selftest.m4 (GDB_AC_SELFTEST): Error out if $development is
not "true" or "false".
* configure: Re-generate.
gdbserver/ChangeLog:
* configure: Re-generate.
gdbsupport/ChangeLog:
* configure: Re-generate.
