Link error happens for valgrind when linking unoptimized libgcc.
Libgcc requires symbol _Unwind_Resume defined in libgcc_eh which
in turn requires pulling in entire glibc. We can't make valgrind
link with glibc due to its design. So don't build libgcc without
optimizations, so that calls to _Unwind_Resume get eliminated.
