    libatomic, libgomp, libitc: Fix bootstrap [PR70454]

    The recent changes to error on mixing -march=3Di386 and -fcf-protection=
 broke
    bootstrap.  This patch changes lib{atomic,gomp,itm} configury, so that =
it
    only adds -march=3Di486 to flags if really needed (i.e. when 486 or lat=
er
isn't
    on by default already).  Similarly, it will not use ifuncs if -mcx16
    (or -march=3Di686 for 32-bit) is on by default.
