From 1ad771d86728ee2ed30e202e9768d8d825f96467 Mon Sep 17 00:00:00 2001

Subject: [PATCH] bpo-36852: proper detection of mips architecture for soft
float
When (cross) compiling for softfloat mips, __mips_hard_float will not be
defined and detection of OS triplet in configure.ac / configure will fail.
This also has to do with the custom detection of the build triplet. Trying
to do this in a more autoconf/autotools manner.
Upstream-Status: Submitted [https://github.com/python/cpython/pull/13196]
