Move libraries version info to the beginning of Makefile.am

(code refactoring)

* Makefile.am (LIBGC_VER_INFO, LIBGCCPP_VER_INFO): New variable; add
comment about the version update rule.
* cord/cord.am (LIBCORD_VER_INFO): Likewise.
* Makefile.am (libgc_la_LDFLAGS, libgccpp_la_LDFLAGS): Use
LIBGC[CPP]_VER_INFO instead the direct hard-coding of version info.
* cord/cord.am (libcord_la_LDFLAGS): Likewise.
