libroot: Make glibc use our math.h.
Only a few definitions (and some "hacks", to force glibc to use __builtin_* where possible) that are not in our math.h remain. This cuts out a lot more of the "bits" headers. No "functional" change intended (but should help fix the build on arches where we do not include __fpclassify, etc. anymore.)
