[PATCH for 4.21 v7 0.5/4] xen/README: add compiler and binutils versions for RISCV-64

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Set the baseline for the compiler and binutils to >=12.2 for GCC and
>=2.39 for GNU binutils, as Xen's GitLab CI will use the Debian 12
container for RISCV-64 testing. Therefore, these versions are expected
to be the minimum supported versions.
