Do you want me to split this further into two commits?

  selftests/x86/Makefile: Per-target configuration of linked libraries

  Targets can set $(LIBS) to specify a different set of libraries than the
  defaults (or no libraries at all).

And:

  selftests/x86/Makefile: Do not pass header files as compiler inputs

  Filtering out .h files avoids accidentally creating a precompiled
  header.

I didn't want to game commit metrics.

Thanks,
Florian
