[Buildroot] [PATCH v3 1/1] package/gdb: host-texinfo needed for full gdb

[Brendan Heading <brendanheading@gmail.com>]

Fixes :
http://autobuild.buildroot.net/results/dd5/dd50ed99abb2c8495def826866b184030953f90e/

.. and many others.

when building the full gdb (ie not just gdbserver) on the host or target
the "make install" phase seems to expect makeinfo (from texinfo) to be
present.

Added a dependency so that the host always depends on host-texinfo, and
the target depends on it if the full GDB is being built. No need to set
ac_cv_prog_MAKEINFO anymore as it doesn't seem to achieve the desired
effect.

v1->v2: fixed for target, removed duplication in gdb.mk. Used better
subject suggested by Vicente.

v2->v3: fix typos, fixed subject to reflect that the issue applies to
gdb in general (host and target).
