ENV.rb: Generalize method for setting CPU flags

All logic has been copied into a new method `set_cpu_flags` that accepts an
additional argument, `flags`, which contains a list of environment variables
for which the CPU flags are to be adjusted.

`set_cpu_cflags` now recalls `set_cpu_flags` and passes `cflags_flags` as the
first argument.
