Work around a binutils bug on powerpc64 where the TOC would not be
properly reloaded when calling _fini() in large binaries with multiple
TOC sections (e.g. GCC), leading to a segmentation fault. Adding -mlongcall
to crt1 flags causes the compiler to emit explicit TOC load instructions
for all function calls, including _fini().
