Update zext.h-01.S

[davidharrishmc]

Remove RV64IB from the ISA string.

The RV64IB ISA causes a compilation string of -march=rv64ib and thus a gcc error "cannot find default versions of the ISA extension 'b'".

This is the only test in riscv-arch-test that specifies RV64IB. I believe it is a typo and should be removed. When I remove it, riscof produces a Makefile that compiles zext.h-01 successfully.

OK, this is another weird case; this should have been caught by CI tests I would think. (or is it GCC that just changed?)

@davidharrishmc Will need a changelog update to merge this. I believe the tests were run with the older gcc before being checked in. Nice catch!

[davidharrishmc]

I'm not sure how to make a changelog entry and associate it with this PR. The entry should say

"Remove RV64IB from the ISA string for zext.h-01 because it is no longer compatible with GCC 12.2"

Thanks for the PR. Updated and merged.
