Initial bsd.gnat.mk

[freebsd-ports at coreland.ath.cx]

Hello.

This is an initial version of 'bsd.gnat.mk'.

A user may set USE_GNAT to 'gnat-gcc' or 'gnat-gpl', currently.

gnat-gcc selects lang/gnat-gcc44 and gnat-gpl selects lang/gnat
as the Ada compiler used to compile ports.

I have made gnat-gcc the default as it supports more architectures
(I've been unable to get gnat-gpl to build on AMD64 as it seems to
specifically lack support for it).

As shown, GNAT_GCC_CFLAGS may also be set. These are optional
compiler flags (like CFLAGS).
