[committed] C-SKY: Define SYSROOT_SUFFIX_SPEC.
Commit Message
The earlier patch
https://gcc.gnu.org/pipermail/gcc-patches/2021-July/575418.html
refine the way to generate sysroot suffix, but it can't find the
right path for all CPUs. The SYSROOT_SUFFIX_SPEC should be defined
to fix it.
gcc/
* config/csky/csky-linux-elf.h (SYSROOT_SUFFIX_SPEC): New.

I think this caused the build failures with build-many-glibcs.py shown by
my bot. SYSROOT_SUFFIX_SPEC should not be defined for a
--disable-multilib build; in such a build you can expect a single sysroot
without a suffix involved. Thus, you should put the SYSROOT_SUFFIX_SPEC
definition in a separate header only used if test "x${enable_multilib}" =
xyes (as in the config.gcc code removed in the older patch you refer to
above), or something similar.

The error is:
/scratch/jmyers/glibc-bot/install/compilers/csky-linux-gnuabiv2/csky-glibc-linux-gnuabiv2/bin/ld: cannot find -lc: No such file or directory
(linking shared libgcc).

Hi Joseph,
Sorry, this is indeed caused by this patch. I tested the multilib scenario, but I didn't test the non-multilib, so I didn't find this problem in time.
Now I have fixed this problem, the patch can be seen in
https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610534.html
Hope it also works for you, If you still have problems, please contact me.
Thanks,
Cooper
