"VECTOR" is not really consistent to how the other configs are named;
RISCV_ISA_V, RISCV_ISA_VECTOR, RISCV_VECTOR?
It'd be RISCV_ISA_V to match the others single letter extentions, right?

Yep.

The toolchain dependency check here also seems rather naive.

Indeed. I can build the code just fine with gcc-11 (and gcc-12), although my reworked patcheset doesn't include all the orig patches including the in-kernel xor stuff.
