I tried hard to have the custom configure script collaborating, but in
the end, it appears critically broken. This is what I tried:

But due to the test setting COMPILER failing, it doesn't set any
ALL_LIBS and thus doesn't build anything (see:
https://github.com/concurrencykit/ck/issues/191).
I also tried patching COMPILER to hard-code it to gcc and export
COMPILER to gcc, but that doesn't work too; it seems the ordering of the
logic in script is wrong.
I'd still keep the changes in, which will make life easier if/when
upstream fixes their script.
Thanks,
Maxim
