toolchain/gcc: Backport patch to fix unconditional MULTIARCH_DIRNAME

This backports the patch for GCC PR target/89587 (gcc's rs6000
configuration unconditionally sets MULTIARCH_DIRNAME, even when
multiarch is disabled).

This currently affects apm821xx and may cause issues when
cross-compiling packages, e.g. Python 3[1].

This includes patches for GCC 8 (with the changelog diff removed);
this change is already included in GCC 9.2 and 7.5.
