[Bug other/32154] New: sim-crt0.o isn't found during configure due to missing -L or -B

[rask at sygehus dot dk]

I configured GCC like this:

/n/08/rask/src/gcc/configure --target=powerpc-unknown-eabisim --disable-nls
--with-newlib --enable-sim --disable-shared --enable-languages=c,c++,objc

When make runs configure in the target subdirectories, sim-crt0.o from libgloss
isn't found:

configure:2362: checking for C compiler version
[...]
configure:2397: /home/rask/build/gcc-powerpc-unknown-eabisim/./gcc/xgcc
-B/home/rask/build/gcc-powerpc-unknown-eabisim/./gcc/ -nostdinc

such file: No such file or directory
collect2: ld returned 1 exit status
configure:2400: $? = 1

I see this in several target subdirs' config.log:
boehm-gc/config.log
libgcc/config.log
libiberty/config.log
libssp/config.log
libstdc++-v3/config.log

The cause of the problem is that the necessary -L or -B option pointing to the
libgloss/rs6000 directory is missing. The result is that link tests fail.

The same thing happens when configuring with --target==mcore-unknown-elf, only
the startup file is crt0.c instead of sim-crt0.o.

Patch to add -L and -B as necessary

This happens on all targets except m32c-*-*. I'm testing the attached patch.

Note that m32c puts *.ld files in the *build* directory, not the
*source* directory, unlike most targets.  The m32c source directory
only has templates.

Also, please keep the comments around.  You're deleting them from the
m32c case, but not adding equivalent ones in the generic case.

Patch v2 to add -L and -B as necessary

I believe I have covered boths cases of linker script placement.
The comments ended up a lot farther away from the lines they were supposed to
comment than intended.
The attached patch fixes a few things that I didn't get right in my first
attempt.

m32c still needs -L$$r/$(TARGET_SUBDIR)/libgloss/m32c to find r8c.ld in the
build directory.  Your patch would only search in the source directory.  Be
careful with -B vs -L, and $$r vs $$s.

You've also removed the special flags needed for a mep build.

According to the documentation, -B passes -L to the linker, so there is no need
to pass both. It seems to work as documented.

Patch v3 to add -L and -B as necessary

This patch should fix the mep* case that I accidentally deleted.

Bug bootstrap/28949 is also similiar to this one.
Btw, this bug is the root cause of the error message 'Link tests are not
allowed after GCC_NO_EXECUTABLES' for newlib targets, so it should show up in
searches for that message, which it will now.
