Maybe not that simple as other archs are involved. AFAICS before the
patch the compilation should have the default optimization level; and
after it will have "none" unless FDLIBM_CFLAGS is set. Seems odd that
"none" would cause a regression like this. Can you generate before/after
build logs to check the actual flags?
