Very recent libstdc++ breakage: testsuite_shared.so cannot be built anymore

[Paolo Carlini]

Hi,

everything was fine until this morning, now upon make-check in the v3
dir, during the final link for testsuite_shared.so, ld spills:

relocation R_X86_64_PC32 against symbol
`__gnu_cxx::__common_pool<__gnu_cxx::__pool, true>::_S_get_pool()' can
not be used when making a shared object; recompile with -fPIC

This is happening, for example, on x86_64-linux, binutils
2.19.51.20090527-10.26.4

Paolo.
