On some architectures when building with -O0 the __register_frame symbol fails to get optimized out which can cause linking failures when building glibc. To fix this set -O1 for GCC target libs when building with glibc and BR2_OPTIMIZE_0 on the problematic target architectures. This was reported both to GCC [1] and glibc [2] upstream. It is not entirely clear yet where the bug lies exactly. At the moment the assumption is that it's GCC, so create a symbol BR2_TOOLCHAIN_HAS_GCC_BUG_107728. This issue only seems to occur when linking glibc, not with anything else, so only compile libgcc from host-gcc-initial with -O1.
