[Bug 1522726] Re: [regression] Linking mir_unit_tests.bin now takes a very long time (minutes) even on a fast machine (previously just seconds)

[Daniel van Vugt]

I *think* I can now exclude differences in libraries, as today I managed
to build the code on xenial:amd64 with a chroot of wily:amd64. So the
change in libraries on xenial does not seem to be the problem. It's
still slow.

So assuming than analysis is correct, it's probably only the compiler
difference left to check.
