Does not work properly on Mac

[mouse07410]

@floodyberry this code does not work properly on Mac.

Mac OS X 10.10.5 (and 10.11.3). Xcode-7.2.1, and gcc-5.3 (Macports-installed).

Symptoms:

• Unable to properly detect what processor it is running on. In particular, seems stuck in 32-bit mode.
• Unable to detect what compiler to use (choices are clang and gcc).
• Does not know that gcc on Mac OS X (especially the Macports-built one) needs -Wa,-q switch to invoke the correct assembler, otherwise none of the extended Intel instruction set is properly parsed/compiled.
• Insists on building fat architecture on Mac (I've been running 64-bit only for I don't remember how long). This of course fails because most (all?) of my libraries are 64-bit only, and have no corresponding 32-bit object files.
• By design has no controls that a user could tweak to get over these quirks and make this stuff actually work.

supercop-20141124 has been running almost five days uninterrupted, producing zero useful output. See the attached bench/machine-name/log and nohup.out (yes, nohup.out is empty).
