Comment (by acjones8):
Thanks for the tips! I didn't know about the disable silent rules option.
I added the `--disable-silent-rules` flag and did `configure.args-append
-faltivec` for cflags, cxxflags, and cppflags, but unfortunately none of
them fixed the issue. Because of the disable-silent-rules flag, I can see
that -faltivec is in the list of options passed to the compiler, so it
doesn't seem like the build system is causing the issue.

'vec_or'?

}}}
I looked up other options in the GCC manual related to altivec support,
and I found a `-maltivec` option. I gave it a try just in case, but it
didn't work either. I wondered if maybe something's wrong in how GCC
handles altivec support, so I wrote a very short test program that uses
`vec_add()` to add two vector ints together and prints the result. I've
never worked with SIMD before, but it gives the correct results even after
I tweak the input numbers, and it recognized `#include <altivec.h>`
without me needing to manually pass in `-faltivec`. Plus, if OpenSSL uses
altivec to accelerate encryption as well, I've been able to compile that
without issues.
