[m-rev.] trivial diff: avoid ambiguous overloading

[Julien Fischer]

Zoltan fixed this on the main branch a while back - it doesn't
seem to have been showing up on Linux/OS X but did pop up
when building the release branch on Windows.

Estimated hours taken: 0.1
Branches: release

compiler/modecheck_unify.m:
	Fix an ambiguity that shows up when compiling with
	intermodule-optimization enabled.

Julien.
