[gmp] [powerpc] GMP build is broken because asm {...} syntax has been removed from latest toolchains

[Torbjorn Granlund]

What version of GCC comes without this support?

I have not head of said segher before.  Does he make changes to the
official GCC repository?  One should point out to him, and perhaps the
GCC team, that this featue is in active use.  Any non-trivial inline asm
requires dependency on GCC internals.  One basically cannot define
anything except register operands without knowing the various magic
letters.  See any asm macro in GMP's longlong.h.
