[patch][arm][FreeBSD] add support for armv7*-*-freebsd*


Hi all,

I'm going to commit this patch if no objections pop up.

We (FreeBSD folks) have added a new target tripplet for armv7*-*-freebsd*
To be able to build GCC we need the below changes.

Results will be posted to the usual place, once they completed....

While here I remove an obsolete define.

I'll post similar patches for gcc-7, gcc-6 and gcc-5 branches.
They differ a bit...

Please speak up if you do not agree.

TIA,
Andreas

	* config.gcc (armv7*-*-freebsd*): New target.
	(armv6*-*-freebsd*): Remove obsolete TARGET_FREEBSD_ARMv6 define.
