This is similar to x86 (da75c1b180) and powerpc (32ea729996) mathinline.h removal. The required macros to build the fpu routines are moved to mathimpl.h, while the inline optimization macros for atan, tanh, rint, log1p, significand, trunc, floor, ceil, isinf, finite, scalbn, isnan, scalbln, nearbyint, lrint, and sincos are removed. The gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94204 was created to track builtin support. Checked with a build against m68k-linux-gnu, resulting binaries are similar with and without the patch.
