Only use linker option --no-warn-execstack if supported

The --no-warn-execstack is new in ld(1) version 2.39; only use the
option if the linker supports it.

* Makefile: Only add "-Xlinker --no-warn-execstack" to LDFLAGS for
  various programs if we can successfully run a compiler with that
  linker flag.
