[PATCH] ada: GNU/kFreeBSD x86_64 support

- Subject: [PATCH] ada: GNU/kFreeBSD x86_64 support
Hi,
Please find below a patch to add Ada support on GNU/kFreeBSD x86_64. The
testsuite shows no regression compared to the x86 version.
Note that system-freebsd-x86_64.ads has already been sent [1] to this
list but not committed yet. It's the same file as system-freebsd-x86.ads
with the comment in the header changed, and s/32/64/ on two lines.

2009-08-17 Aurelien Jarno <aurelien@aurel32.net>
* gcc-interface/Makefile.in: Add Ada support for
GNU/kFreeBSD x86_64.
* system-freebsd-x86_64.ads: New file based on
system-freebsd-x86.ads.
