[Bug libgomp/43499] New: libgomp.fortran/appendix-a/a.22.7.f90 and libgomp.fortran/omp_parse3.f90 fail on powerpc-unknown-linux-gnu with -fpic

[ghazi at gcc dot gnu dot org]

When running the testsuite on powerpc-unknown-linux-gnu with extra passes
containing -fpic I get the following additional error on the 4.3 branch:

Running target unix/-fpic
FAIL: libgomp.fortran/appendix-a/a.22.7.f90  -Os  (test for excess errors)
UNRESOLVED: libgomp.fortran/appendix-a/a.22.7.f90  -Os  compilation failed to
produce executable
FAIL: libgomp.fortran/omp_parse3.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  (test for excess errors)
UNRESOLVED: libgomp.fortran/omp_parse3.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  compilation failed to produce executable

It only triggers with -fpic, -fPIC does not trigger.  The error only occurs on
the 4.3 branch, later versions (4.4 branch and 4.5 trunk) do not show the
error.

Testsuite results showing the error:
http://gcc.gnu.org/ml/gcc-testresults/2010-03/msg01996.html

The gcc.log file shows this message for both failures:
/usr/bin/ld: BFD 2.17 Debian GNU/Linux internal error, aborting at
../../bfd/elf32-ppc.c line 6071 in ppc_elf_relocate_section
/usr/bin/ld: Please report this bug.

While binutils ld shouldn't crash, I think we should see if GCC is producing
erroneous output too.
