Some of the command line options may be unnecessary so I'll drop this patch. Matthew

Ping. Updated patch attached, I've broken the over-long lines added to arm-arches.def and arm-fpus.def.

Support has been enabled in binutils for ARMv8.1 for the architechure, using the name "armv8.1-a". This patch adds support to gcc for specifying an ARMv8.1 architecture using options "-march=armv8.1-a" and "-march=armv8.1-a+crc". It also adds the FPU options "-mfpu=neon-fp-armv8.1" and "-mpu=crypto-neon-fp-armv8.1", to specify the ARMv8.1 Adv.SIMD instruction set. The changes set the apropriate architecture and fpu options for binutils but don't otherwise change the code generated by gcc. Tested for arm-none-linux-gnueabihf with native bootstrap and make check. Ok for trunk?
