Move compiler-specific code to a local compiler.h file. CONFIG_AEABI

is the API for aarch64. Deal with unresolved references emitted by
GCC. Optimize handling of fallback calls. Most notably add unlikely
nullptr checking to __vdso_gettimeofday, if tv null no need to
proceed to fallback, as vdso is capable of filling in the tv values.
nit: last sentence should have read 'filling in the tz values.'
