I don't think you should remove those two lines - the patch I've been 
using is:

*** ./scripts/kconfig/Makefile.dist     2005-08-25 10:41:16.713246000 +0100
--- ./scripts/kconfig/Makefile  2005-09-23 14:47:45.815370614 +0100

!         LIBPATH=$$DIR/lib/$$($(HOSTCXX) -print-multi-os-directory); \
         if [ -f $$LIBPATH/libqt-mt.so ]; then LIB=qt-mt; fi; \
