ba5b9a8 to9c6b46aCompareWide versions of GCC (≤13) produce ambiguous bugs with compiler target attributes when`-mcpu/host` flags are provided via environment variables or via Meson build,leading to an inability to raise the default baseline to POWER10.This is fixed by enabling the newly added Highway option `-DHWY_DISABLE_ATTR` to address the issue,as reported to Highway. This patch also fixes the Clang build bug reported by explicitlyadding `-mvsx` along with `-mcpu`.
