This happens when compiling arts (KDE sound server) 1.5.4:
/usr/bin/ld: ./flow/gslpp/.libs/libgslpp.a(datahandle.o): relocation
R_X86_64_PC32 against `vtable for GSL::WaveDataHandle' can not be used when
making a shared object; recompile with -fPIC
However, libgslpp.a and datahandle.o were built using -fPIC.
This is the extract of the build log for building datahandle.o and libgslpp.a:

This worked correctly before; binutils version is 2.17.50.0.3 (just in case
this is a binutils bug that just happened not to show up with earlier gccs).
