Seems wise. The binutils-2.47 release is a week or so away; they
typically don't want new features this late in the process. There'll be
a binutils-2.48 late this year or early next year (before gcc-17). So
we should make sure the bits get into binutils-2.48, then we can
re-enable this feature in gcc in time for gcc-17.
We're in a similar position with one of the spacemit extensions in the
isa string that isn't supported by gas/binutils.
Anyway, I'll push this to the trunk momentarily. Thanks again.
