gmp 4.1 on OpenBSD

[Christian Weisgerber]

1.
OpenBSD/sparc64 is a true 64-bit platform.  Currently, gmp's configure
script doesn't recognize OpenBSD/sparc64 and falls back to a Linux-
inspired 32-bit default that builds but doesn't work.  I copied the
settings that appeared relevant from the Solaris section and with
the following change gmp 4.1 builds and tests fine on OpenBSD/sparc64.
I strongly suspect that the same patch is required for NetBSD/sparc64
and FreeBSD/sparc64.

OpenBSD/i386 is still an a.out platform and it does require GSYM_PREFIX
('_') for _GLOBAL_OFFSET_TABLE_, cf. mpn/x86/README.  I don't know
whether this is compatible with other i386/a.out platforms.
