Comment (by zooko):

 Hm... So with {{{CRYPTOPP_DISABLE_ASM}}}, the quick self-test of SHA256
 segfaults at startup, on the "atlas" ubuntu box and on midnightmagic's
 netbsd box:

 https://tahoe-lafs.org/buildbot-
 pycryptopp/builders/atlas1%20natty%20syslib/builds/133/steps/version/logs/valgrind

 But only when they are linking against the system-provided libcryptopp
 instead of the embedded cryptopp. I guess it is really necessary that the
 {{{CRYPTOPP_DISABLE_ASM}}} macro be set the same when we build pycryptopp
 as when the libcryptopp.so that we're linking against was built. It is a
 safe bet (I guess) that it is never set for any system-provided
 libcryptopp.so, so I'll just make it so that our setup.py sets
 {{{CRYPTOPP_DISABLE_ASM}}} only when it is building the embedded Crypto++.
