Ignore stderr in AT_CHECK for readelf stderr warnings

Aha, OK now I understand how to replicate it.
./configure CC="gcc -O2 -g"
Will do the same. Always run gcc with -O2 even in the testsuite.

Even though I think you should not add extra compiler flags to the testsuite I
see how if you do warnings from readelf would be an issue.

Luckily it is easy to ignore stderr warnings with AT_CHECK.
Could you try the attached patch?

If there is no bug yet, we should file a binutils bug against readelf
(apply_relocations) should handle R_RISCV_SET_ULEB128 and R_RISCV_SUB_ULEB128
