### 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.
