Remove the GXEMUL support.
gxemul was a nice stop-gap while qemu support for mips was firmed up. Now MALTA* + qemu is the platform of choice retire gxemul support. It's unknown when this was last confirmed working. Discussed on: freebsd-mips@ Differential Revision: https://reviews.freebsd.org/D18543
