Hello,
This patch adds a new --enable-gdbserver=yes/no/auto command-line switch
in gdb/configure. The primary purpose is to allow a user to disable the
build & install of gdbserver when not desired. It also allows the user
to request gdbserver in which case the configure script will abort if
automatic building of gdbserver is not supported for that configuration.
The default keeps things as is: We automatically build gdbserver if
building for a native configuration and if gdbserver is supported for
that configuration.
gdb/ChangeLog:
* configure.ac: Add support for --enable-gdbserver.
* configure: Regenerate.
This was tested on x86_64-linux with the following combinations:
- ./configure
- ./configure --enable-gdbserver
- ./configure --enable-gdbserver=toto [error]
- ./configure --disable-gdbserver
- ./configure --target=erc32-elf
- ./configure --enable-gdbserver --target=erc32-elf [error]
- ./configure --disable-gdbserver --target=erc32-elf
Any objection to this change? I'd like to commit sometime in
the next few days if not.

No objection after a month, so I checked this one in.
