Log Message:
add gnat-aux-20110125, an Ada compiler gased on a gcc-4.6 snapshot, from
John Marino, originally per PR pkg/44436, slightly updated

for i386/amd64, comes with a bootstrap which doesn't need an Ada compiler
on the pkg build system (fetches a bootstrap binary from MASTER_SITE)

There seems to be some incompatibility with the binutils/libgcc_s
on NetBSD-current, leading to warnings. Not fatal, but should be
investigated.
