I cannot really decipher libs/context/build/Jamfile.v2, but I can see
that the only mentions of MIPS in there relate to the o32 ABI, whereas
we target n32.

Another thing that=E2=80=99s fishy in the build log is that, at the beginni=
ng of
the build phase, we see:

--8<---------------cut here---------------start------------->8---
Component configuration:

    - atomic                   : building
    - chrono                   : building
    - container                : building
    - context                  : not building
    - coroutine                : not building
--8<---------------cut here---------------end--------------->8---

Yet it attempts to build =E2=80=98context=E2=80=99.

I think we could try another option, which is to configure with

  --without-libraries=3Dcontext

like openSuSE does in some cases:

   https://build.opensuse.org/package/view_file/devel:libraries:c_c++/boost=
/boost.spec

Could someone try that?

If that fails, or if nobody can test it, let=E2=80=99s just do #1.
