On m68k, gcc creates short assembler branch insns, and expects the
assembler to adapt them to the distance. m68k gas appears not to do
that for fpu branch insns, resulting in an out-of-range FPU assembler
branch instruction error in "ext/re/re_exec.c".
As a workaround, building with "-Os" instead of "-O2" reduces the size
of the object file enough to allow short branches.
See PR toolchain/45439.
