binutils: build host-texinfo if needed

This commit adds the dependency on host-texinfo to binutils, when the
source is fetched from Git. Thanks to this, we can remove the
0800-Docs-Prevent-build-failures-when-makeinfo-is-missing.patch patch
from the ARC-specific version of binutils.

-Subject: [PATCH] Docs: Prevent build failures when "makeinfo" is missing
-
-Build failed when "makeinfo" was missing on the build host.
-This was happenning because "makeinfo" is required to build .info targets
-and make exited with error. But missing "makeinfo" only stops us from
-building docs ("missing" script already throws a warning on that regard).
-Let's continue to build other targets.
-
-Now exit code of the script called "missing" is checked.
-The value 127 means that "makeinfo" is not available on the build host.
-
-So when such value occurs 0 is returned to the top level makefile.
-Documentation is not being built but further build of binutils continues.
