Arun Raghavan 98454ed265 build: Add architecture checks for x86 and ARM
On x86, SSE optimisations are always compiled in, and used based on
runtime checks.

On ARM, we try to autodetect NEON support (with an option of runtime
detection). This has not been build-tested on ARM yet.

This leaves MIPS to be done.
