At the end of the log is says:

So the tests didn't fail, they just timed out. Unfortunately the mips
big endian buildds + porterbox (currently) don't have FPUs, so anything
FPU intensive requires the kernel to emulate the FPU instructions and
it's extremely slow.

Assuming that it what's causing the timeouts, there's not a huge amount
that can be done about it at the moment short of disabling the
testsuite (which you probably don't want to do). I would advise you to
just leave it until there are some better machines to build it on.
