--- Comment #2 from Michael Meissner <meissner at gcc dot gnu.org> --- One other possibility is to just remove the code that checks TARGET_LIBC_PROVIDES_HWCAP_IN_TCB, given that when we use it there is a reference to __parse_hwcap_and_convert_at_platform in the code. That won't be satisified unless you have a new enough glibc. Though it may be friendlier to warn the user if GCC wasn't configured to use the newer glibc.
