enable XMM registers. Historically address of the capability vector copy
was exposed to application through OPENSSL_ia32cap_loc(), but not
anymore. Now the only way to affect the capability detection is to set
-OPENSSL_ia32cap envrionment variable prior target application start. To
+OPENSSL_ia32cap environment variable prior target application start. To
give a specific example, on Intel P4 processor 'env
OPENSSL_ia32cap=0x16980010 apps/openssl', or better yet 'env
OPENSSL_ia32cap=~0x1000000 apps/openssl' would achieve the desired
AVX2 | 2.22 | 2.10 | 3.1
AVX512 | 2.25 | 2.11.8 | 3.6
+B<OPENSSL_ia32cap> is a macro returning the first word of the vector.
