Makefile: Add a DISABLE_CLOCK_GETTIME option
Allows to force-disable the use of clock_gettime() at build time,
falling back to busy-looping for udelay. This is useful when building
for systems which are known to lie about the resolution of
clock_gettime(), such as Linux guests running under the Muen Separation
Kernel.
