[OE-core] [PATCH 1/3] Allow texinfo, texinfo-native recipes to build w/o host system's Texinfo utils

[Max Eliaser]

This is necessary for the eventual removal of Yocto's current dependency on
the host system's Texinfo utilities.

The Texinfo suite's build system actually already has a self-bootstrap system
it uses when cross-compiling or when Texinfo binaries aren't already
available. This had been suppressed with patches, but this commit removes
those patches and alters the recipe to make the bootstrapping work properly.

This adds no real overhead for the texinfo-native recipe, but it does mean
that the target architecture recipe actually builds some native binaries
before building the cross-compiled ones. I find this extra overhead
acceptable, since I doubt too many people using Yocto are shipping
images with cross-compiled versions of the Texinfo utilities.

The removal of these patches also allows us to make the target arch texinfo
recipe no longer depend on texinfo-native, since we're going back to using the
built-in bootstrapping process as the Texinfo upstream maintainers intended.

-there isn't any need to try and build the required native texinfo binaries
-before cross-compiling. This simplifies the recipe somewhat!
