Portage is overriding my preference of -Os and implicitly declaring that glibc should be compiled with -O3. I see that my parameter is being passed to the compiler, but after my custom CFLAGS the build process is passing -O99, overriding my flag. Where's the feet?

Please leave the toolchain CFLAGS alone, if you dislike -O99, then remove glibc-omitfp from your use. The ebuild/eclass overrides/strips glibc flags as needed to ensure a sane toolchain.
I haven't messed with the "toolchain CFLAGS". I set the global CFLAGS in make.conf. Why is "-O99" more sane than "-Os" or even "-O2"? This is still a bug, as -O99 isn't even a valid parameter.
Sure it is valid. glibc/gcc won't honor your CFLAGS, live with it.
