   4 Subject: [PATCH] bpo-36852: proper detection of mips architecture for soft
   5
   6  float
   7
   8 When (cross) compiling for softfloat mips, __mips_hard_float will not be
   9 defined and detection of OS triplet in configure.ac / configure will fail.
  10
  11 This also has to do with the custom detection of the build triplet. Trying
  12 to do this in a more autoconf/autotools manner.
  13
  14 Upstream-Status: Submitted [https://github.com/python/cpython/pull/13196]
