It seems that the behaviour of "grep ''" is the same as "cat"; copy all input
to stdout. Can we simply remove the grep part?

-_${def:C/=.*$//}_CMD=  ${PKG_INFO} -qp ${def:C/^.*=//} 2>/dev/null | ${AWK} '{ print $$2; exit }' | grep '' || ${ECHO} ${${def:C/=.*$//}_DEFAULT}
+_${def:C/=.*$//}_CMD=  ${PKG_INFO} -qp ${def:C/^.*=//} 2>/dev/null | ${AWK} '{ print $$2; exit }' || ${ECHO} ${${def:C/=.*$//}_DEFAULT}

After I applied above change, I tried "make package" in databases/php-mysql,
which defines EVAL_PREFIX in its Makefile, and successfully finished.
