This patch adds support for FreeBSD ARM in gas.

Before FreeBSD-8 there was/is no arm support from the OS side.
FreeBSD-9.x added ARM support but only for the OABI.
From FreeBSD-10 upwards there is EABI support.

    * Makefile.am: Add FreeBSD ARM support.
    * Mafefile.in: Regenerate.
    * configure.tgt: Add FreeBSD ARM support.
    * config/te-armfbsdeabi.h: New file.
    * config/te-armfbsdvfp.h: Likewise.
