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.
