Subject: [PATCH 1/1] kbuild: solve the DSO link change issue

when make menuconfig, it reports this error:

/usr/bin/ld: scripts/kconfig/lxdialog/checklist.o: undefined reference to symbol 'acs_map'
/usr/bin/ld: note: 'acs_map' is defined in DSO /lib64/libtinfo.so.5 so try adding it to the linker command line
/lib64/libtinfo.so.5: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

due to the DSO link change, we must explicitly link against every library needed.
