Using --enable-64-bit-words may lead to some speedups on 64bit processors too:

Removing the switch "--disable-see" does not affect compilation: `flac` package builds fine!
What was the reason behind the addition of that switch?

flac 1.3.4-1 switched from ./configure to cmake, going with the default which is enabled SSE2.

Side note: Going by the package history (as far as it goes on GitHub), --disable-sse seems to have been a leftover from before 2008.
