[PATCH][OBVIOUS] Fix genversion linker error.

[Martin Liška]

When renaming gcov-iov to genversion I forgot one hunk that led
to the following linker error:

ld: error: build/genversion.o: requires dynamic R_X86_64_32 reloc which may overflow at runtime; recompile with -fPIC

It's a copy&paste error and I'm going to push it.
