main/binutils: add mips support

* Remove hash-style-gnu.patch in favor of the patch adding a configure flag for it from upstream
* Add gold-mips.patch from Debian, which makes gold configure correctly for MIPS64 targets
* Use CTARGET_ARCH instead of CARCH to correctly determine whether to enable the x86_64-pep target or not
