Yes, my intention was to use one cache variable for the test, as opposed
to one per compiler, which should fix this to take the result of the
first compiler (C if not disabled).

Strictly speaking, that is not precise enough: the user could be using
different linkers for different compilers.  I don't think we need to
support such a setup on GNU/Linux, though.
