net-im/freetalk: update to version 4.1
Differences from submitted patch:
- Add License information.
- Remove the NLS option because --disable/enable-nls had no effect (binary still linked to libintl.so.8). There were also no %%NLS%% lines in pkg-plist.
- Add libgc-threaded.so:devel/boehm-gc-threaded to LIB_DEPENDS.
- Remove GH_COMMIT definition; GH_TAGNAME is defined.
- Add autoreconf, gettext-runtime, localbase, makeinfo, and readline to USES=.
- With localbase, CPPFLAGS+= and LDFLAGS+= are no longer necessary.
- With autoreconf, pre-configure target is no longer necessary.
- Remove info-related lines from pkg-plist and set INFO.
