This (or some variant thereof; haven't checked), became part of
commit r13-4704-g1eee94d351774cdc2efc8ee508b82d065184c6ee
"Merge modula-2 front end onto gcc".
For build-tree testing ('$gccpath != ""'; such as standard 'make check'),
'gm2_link_flags' takes care to set up paths to a number of libraries that
may be necessary:

However, this misses compiler libraries (such as libgcc, which libstdc++
may depend on). For example, I see my x86_64-pc-linux-gnu '-m32' testing
not pick up the build-tree libgcc, but instead some random system one,
which (expectedly) doesn't satisfy requirements of other build-tree
libraries:
[...]/build-gcc/gcc/testsuite/gm225/m.x0: /lib/i386-linux-gnu/libgcc_s.so.1: version `GCC_7.0.0' not found (required by [...]/build-gcc/x86_64-pc-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so.6)
..., and thus a lot of execution FAILs.
To cure that, OK to push the attached
"For Modula-2 build-tree testing, also set up paths to compiler libraries"?

Hi Thomas,
many thanks - yes LGTM,

Subject: [PATCH] For Modula-2 build-tree testing, also set up paths to
compiler libraries
Currently, 'gcc/testsuite/lib/gm2.exp:gm2_link_flags' doesn't set up
paths to compiler libraries (such as libgcc, which libstdc++
may depend on). For example, I see my x86_64-pc-linux-gnu '-m32' testing
not pick up the build-tree libgcc, but instead some random system one,
which (expectedly) doesn't satisfy requirements of other build-tree
libraries:
[...]/build-gcc/gcc/testsuite/gm225/m.x0: /lib/i386-linux-gnu/libgcc_s.so.1: version `GCC_7.0.0' not found (required by [...]/build-gcc/x86_64-pc-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so.6)
..., and thus a lot of execution FAILs.
As seen in a number of other '[...]_link_flags' procedures, the standard idiom
seems to be to also consider 'gcc-set-multilib-library-path' for
'ld_library_path'.
gcc/testsuite/
* lib/gm2.exp (gm2_link_flags) [$gccpath != ""]: Also consider
'gcc-set-multilib-library-path' for 'ld_library_path'.
