Let's suppress the warnings in assembly files by adding non-executables
stack markings. This fixes at least systemd build which uses '-Wl,--fatal-warnings':

Turns out we actually need setjmp in one of gnu-efi's prominent

users, and it seems to make more sense to put it here than in
the application.

All of these are derived from the Tiano code, but I re-wrote the
x86_64 one because we use the ELF psABI calling conventions instead
of the MS ABI calling conventions.  Which is to say you probably
shouldn't setjmp()/longjmp() between functions with EFIAPI (aka
__attribute__((ms_abi))) and those without.
