[patch][arm][FreeBSD] gcc-7 branch: add support for armv7*-*-freebsd*

[Andreas Tobler]

Hi all,

here is the patch witch adds support for armv7*-*-freebsd* on the gcc-7 
branch.

The difference towards trunk is the target_cpu_cname.

I'll commit this one if no objections pop up.
TIA,

Andreas

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