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’s fishy in the build log is that, at the beginning 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 ‘context’.

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

  --without-libraries=context

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’s just do #1.
