Why will it break? BOOT_CFLAGS is only used for stage2 and 3.
Oh! I see! The problem is that, if you use a non-GCC bootstrap
compiler and pass CFLAGS to this compiler, that GCC wouldn't
understand, bootstrap would fail to build stage2.
Point taken. Your patch is perfectly correct. The approach I
proposed would be desirable, from a standards perspective, but it's
unworkable for bootstrapping.
