small patch for liblua/Makefile

[olli hauer <ohauer () gmx de>]

In nmap/Makefile.in CC=$(CC) is set, however this will be not honored in liblua/Makefile

lua_build: $(LIBLUADIR)/Makefile
        @echo Compiling liblua; cd $(LIBLUADIR) && $(MAKE) liblua.a CC="$(CC)" MYCFLAGS="$(CFLAGS) @LUA_CFLAGS@"


The following patch will allow to overwrite CC in liblua/Makefile
