kbuild: check if we can link gettext not just compile
cygwin provides the header file but the lib file needs to be added manually. A generic fix is to check if we can compile and link a program that uses gettext() and if it fails fall back to NO_NLS. International users of cygwin may have to specify HOST_LOADLIBES := "-lintl" on the make command line. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
