app-misc/mc: workaround linkage against internal gettext, bug #693850

The underlying issue is lack of support of linking in static
gettext into libmc.a due to a deficiency in m4/gettext.m4 (see
upstream bug for more details).

The workaround is to manually link bundled gettext into every
final binary. It fixes default case for musl but does not fix
the underlying issues. Let's leave fixing those to upstream.

+Subject: [PATCH] Linking fix for non-default gettext package
+
+mc lost the linking game if gettext package pulled from outside of system paths.
+(Pulling can be done by suitable C-/CPP/LDFLAGS settings)
+
+Furthermore gettext package depends on libintl (if system lib
+don't provide needed functions) then gettext prepare INITLIBS/LIBINTL variable
+for working libintl pull in from gettext libdir.
+
+https://www.gnu.org/software/gettext/FAQ.html#integrating_undefined
+
+Let respect LIBINTL variable at linking (it is empty if not needed).
+
+Failure example for Solaris 10 with non-system-default gettext package:
+
+Undefined                       first referenced
+ symbol                             in file
+ libintl_bind_textdomain_codeset     ./.libs/libinternal.a(args.o)
+ libintl_gettext                     main.o
+ libintl_textdomain                  main.o
+ libintl_bindtextdomain              main.o
+ libintl_ngettext                    ./.libs/libinternal.a(midnight.o)
