python3: Fix/expand platform triplet detection

Currently, configure does not find the correct platform triplet for musl
as the default build/host values passed by OpenWrt buildroot does not
contain the text "linux-musl".

This uses python/cpython#96001 (currently in
draft status) as a base (patch retains changes to configure.ac but
removes changes to configure), and fixes/expands the detection for mips
soft float and mips musl.
