dynamic CPU detection for libgcrypt assembly code?

[Hans-Christoph Steiner]

Hey,

Its great to see all that work being done adding assembly optimizations to
libgcrypt, it should make a really big difference on mobile devices.  My
question is whether there is any kind of dynamic CPU detection that would
enable certain modules, like ARM NEON code?  We'd like to include the NEON
code, but if the same binary won't work on armv7 chips that don't have NEON,
then its a showstopper for us.
