    x86-64: Don't use SSE resolvers for ISA level 3 or above

    When glibc is built with ISA level 3 or above enabled, SSE resolvers
    aren't available and glibc fails to build:

    ld: .../elf/librtld.os: in function `init_cpu_features':
    .../elf/../sysdeps/x86/cpu-features.c:1200:(.text+0x1445f): undefined
reference to `_dl_runtime_resolve_fxsave'
    ld: .../elf/librtld.os: relocation R_X86_64_PC32 against undefined hidden
symbol `_dl_runtime_resolve_fxsave' can not be used when making a shared object
    /usr/local/bin/ld: final link failed: bad value

    For ISA level 3 or above, don't use _dl_runtime_resolve_fxsave nor
    _dl_tlsdesc_dynamic_fxsave.

    This fixes BZ #31429.
