Ppc64el builds using GCC 15 fail without upstream patch
37c08e5528f6 ("pre-release workaround for PPC TestIntegerMaskedDiv:
Unpredictable1")
With the patch there are test failures:
The following tests FAILED:

** Description changed:
+ Highland fails to build on source on the ppc64el and riscv64
+ architectures.
+
In GCC 15.2 we have enbabled RVA23 extensions including vector
instructions.
When trying to rebuild the package an error occurs. This has been
reported to GCC upstream in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121512.
Since release 1.2.0 highway has received RISC-V vector related fixed, e.g.
9cff02ac65ac ("Fixes to compilation errors with RVV with EMU128 or SCALAR
baseline")
