Make lang/nawk building on -current again.

I didn't really take the patches from the PR, since 95% of them
where tab to space conversions. Also tweaked the makefile to use
${CC} instead of cc. The distinfo change is because of the rollout
of a new version, of which the Makefile was already changed but the
distinfo not.
