You can easily find this out by grepping the .h files for different archs.

In plain English, most build targets result in DES_BS_ASM being 0, but
many if not most of the actually running builds have it at 1 - since we
have asm code for the most common archs (x86 with MMX or SSE2, and
x86-64), except when building with OpenMP support (since the asm code is
currently not MT-safe).

That's correct.
