[PATCH] Makefile: set USE_PIC on Linux x86_64 for linking with Git.xs

In commit 6294a10 it was noted that "on x86-64 it seems that Git.xs does not link without compiling the main git objects with -fPIC". Set it therefore automatically on this platform.

This patch does this only for _Linux_ x86-64, as that is the only x86-64 platform I have access to. But it might very well make sense on other x86-64 platforms, please test and report if you have such a platform.

This applies to 'pu'. It is an amended version from an earlier one
with a simplification from Junio and a clarification why it is Linux
specific at the moment. The title was also slightly improved.
