Patch to fix bug 892

This commit fixes bug 892 which requests that x86 processors use CPUID to
detect processor features rather than use codes paths for multiple operating
systems. It does best guess compile-time checking for POSIX functions and
constants, and should be very portable across POSIX operating systems. I have
tested this code and receive the same results as in wine-0.9.27 and
wine-0.9.29, and checked against /proc/cpuinfo, and the results seem to be
correct.
