Subject: gnu: freetype: Fix cross-compilation.

Previously, the 'remove-reference-to-pkg-config' would break when
cross-compiling because the "/bin/pkg-config" file would not be found.

* gnu/packages/fontutils.scm (freetype)[arguments]: Add alternate
'remove-reference-to-pkg-config' phase for (%current-target-system) as
true.
