message:
  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.
