genksyms: remove Makefile hack

Browse Source 
This workaround was introduced for suppressing the reduce/reduce conflict
warnings because the %expect-rr directive, which is applicable only to GLR
parsers, cannot be used for genksyms.

Since there are no longer any conflicts, this Makefile hack is now
unnecessary.
