The difference towards trunk is the missing of target_cpu_cname which is
solved differently.

I'm aware of the gcc-5 branch status and I will not apply before gcc-5.5
is released. I'll also will not apply on the gcc-5 branch if the branch
gets closed.

If you have any objections, please speak up.


Committed _only_ on the gcc-6 branch: 253604

[patch][arm][FreeBSD] gcc-6/5: add support for armv7*-*-freebsd*

[Andreas Tobler]

Hi all,

and here is the patch for gcc-6/5 branch to add support for 
armv7*-*-freebsd*


The difference towards trunk is the missing of target_cpu_cname which is 
solved differently.


I'm aware of the gcc-5 branch status and I will not apply before gcc-5.5 
is released. I'll also will not apply on the gcc-5 branch if the branch 
gets closed.


If you have any objections, please speak up.

TIA,
Andreas
