Okay, that works as far back as gcc 6.3, so v4 does it that way. The
attribute doesn't seem to be necessary on the inline helpers for
production builds, but they're needed to work with -O0.
Also
- removed the term 'intrinsics' from config variables, since we're not
checking those
- removed the crc intrinsic from the pmull tests
- fixed a failure to restore CFLAGS
- fixed it to work with +crc CFLAGS
For some reason, my CI builds with MacOS are failing on v3 (v2 skipped
the runtime check to get some exposure on CI) with the following, and
running CI from my Github account fails as well, so it's not a
temporary glitch. Adding a __linux__ guard to the runtime check didn't
help, so not yet sure what to make of it.
