[Buildroot] [PATCH 2/3] binutils: get rid of host-texinfo dependency and other documentation tricks

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

The binutils/host-binutils package applied several tricks to avoid building
info documentation. In the worst case, host-texinfo is added as dependency.

However, there is a simpler solution that removes the need for all these
tricks: instruct the makefiles to use a dummy makeinfo command ('true').
