I did that now. While I'm still running some more tests, I already
tested tarball versions 7.10.1 and 7.11.1, and both ARC and Microblaze
git versions. I currently only tested host-gdb, but for all these
cases I can get rid of the host-texinfo dependency with following
extra changes:

GDB_INSTALL_OPTS += MAKEINFO=true
GDB_MAKE_OPTS += MAKEINFO=true
HOST_GDB_INSTALL_OPTS += MAKEINFO=true
HOST_GDB_MAKE_OPTS += MAKEINFO=true

The INSTALL_OPTS were needed for the tarball versions, while the
MAKE_OPTS (and perhaps also the INSTALL_OPTS, not sure) for the git
versions.

I still need to test the (target-)gdb, but I guess it won't make a
difference as the Makefiles are the same.

Is this too simplistic? Am I missing something?

Thanks,
Thomas
