On a system where libintl.h is present, but the NLS functionality is supplied by a separate library instead of the system C library, an attempt to "make config" or "make menuconfig" will fail with link errors, ex: scripts/kconfig/mconf.o:mconf.c:(.text+0xf63): undefined reference to `_libintl_gettext' This patch attempts to correct the problem by detecting whether or not NLS support requires linking with libintl.
