// For Linux, install NASM, run rdrand-nasm.asm, add the apppropriate
// object file to the Makefile's LIBOBJS (rdrand-x{86|32|64}.o). After
// that, define these. They are not enabled by default because they
// are not easy to cut-in in the Makefile.
// For Linux, NASM is optional. Run rdrand-nasm.sh, and then make
// with "USE_NASM" like so: USE_NASM=1 make -j 4. The makefile
// will add the appropriate defines when building rdrand.cpp,
// and add the appropriate object file during link.
