Multilib test problems with libgcc_s in gfortran, libstdc++ tests

[Andreas Jaeger <aj at suse dot de>]

Testing with multilibs on Linux/AMD64 I have the problem that a few
tests in gfortran and libstdc++ fail since the primary installed
compiler is a GCC 3.3 compiler with an older version of
/lib/libgcc_s.so.1.  The compiler builds the following files in the
gcc subdirectory:
./libgcc_s.so.1
./libgcc_s_32.so.1
./libgcc_s_32.so
./libgcc_s.so

But no libgcc_s.so in the "32" multilib directory (which is used for
32-bit x86 code).  But we do link against "libgcc_s.so" (via libc.so)
and therefore the testsuite fails with:

Setting LD_LIBRARY_PATH to .:/builds/gcc/misc/x86_64-suse-linux-gnu/32/libgfortran/.libs:/builds/gcc/misc/gcc:.:/builds/gcc/misc/x86_64-suse-linux-gnu/32/libgfortran/.libs:/builds/gcc/misc/gcc:/builds/gcc/misc/gcc
/builds/gcc/misc/gcc/testsuite/intrinsic_rrspacing.x: /lib/libgcc_s.so.1: version `GCC_3.4' not found (required by /builds/gcc/misc/gcc/testsuite/intrinsic_rrspacing.x)
FAIL: gfortran.fortran-torture/execute/intrinsic_rrspacing.f90 execution,  -O1

Any ideas what can be done here?

Btw. I test with:
RUNTESTFLAGS="--target_board 'unix{-m32,}'" make check
