Minor simplications for src/m/amdx86-64.h.

* m/amdx86-64.h (START_FILES, LIB_STANDARD) [__OpenBSD__]:
For clarity, revert to using fixed /usr/lib rather than $CRT_DIR.
(START_FILES, LIB_STANDARD) [__FreeBSD__]: Merge into the generic case,
since CRT_DIR defaults to /usr/lib.  Suggested by Dan Nicolaescu.
