overlays/mtk: Add back Cadence-removed macro

andrew-mtk · nashif · commit 99ea3118e67e · 2025-03-08T08:22:01.000-05:00
See commit 7144272. There is no "predicted branches" extension in any version of the Xtensa ISA reference I have. Newer versions of Cadence tooling have removed (and presumably deprecated) this symbol, but binutils still relies on seeing it (even just to evaluate to a zero to diable the feature). Really the proper fix would be to patch binutils upstream, but let's have compatible headers here first. Signed-off-by: Andrew Perepech <andrew.perepech@mediatek.com>
