Problem noticed by kurt@ and steven@, patch verified by steven@
Add some WRKSRC/WRKBUILD tweask (though yet pointless, since
SEPARATE_BUILD doesn't work for GHC-related ports).
No change for i386, and it this version never built on amd64 after the
GHC update, so no pkg bump required.

a description of the tokens to be recognised in the form of regular
expressions. It is similar to the tool lex or flex for C/C++.
