Would you please attach the section of the build log that contains the
diff of libopenlibm1.symbols?
It will save me some time on a porterbox.

Could you also have a look at the upstream commit where
src/aarch64_fpmath.h was added [1]?
I'd like to know if we need that as well.

If you have the time, please consider testing these changes on
upstream's current git [2] and submitting pull requests.
