Updating the cross toolchain for mips64el

Added patches from upstream and diff'ed with them. Binutils and
linux-libre-api-headers are already built. GCC Core builts but
`mips64el-unknown-linux-gnu-gcc -v dummy.c` fails because of missing -EL on
i686-pc-linux-gnu-as. Exporting mips64el-...-binutils to the PATH solves the
problem but mips64el-...-ld fails with missing crt*.

No idea why target gcc decides to use the host as instead of the target one,
since the PKGBUILD hasn't fundamentally changed.
