I saw no such problem at 69cb14a0d7, neither for sim nor gdb,
using an x86_64 Debian 7.1.  Info-files *are* being generated
with src-release.sh, as for a release, so your development tools
have to be complete.  You probably expected this kind of
reponse, but still: unless it was a temporary bug fixed between
your test and the commit above, I'd guess your makeinfo tools
are out of date or something similar, which would not be
something you can allow yourself to "give up" on, and just skip
testing.  Pretty please investigate.

Regarding using the gdb create-version.sh for sim, I'd rather we
increase separation between sim and gdb sources than making them
more intertwined like that.

Anyway, I committed the following after testing, building sim
and gdb ("make all"), for each untarring the created tarballs
and respectively building a native gdb and a bfin-elf sim.  The
need for gdb/common/create-version.sh should be obvious, but
JFTR, you'll otherwise get:
/bin/bash /tmp/fix/s/s2/sim-7.9.50.20150415/sim/bfin/../../move-if-change tmp-tmap.c targ-map.c
touch stamp-tvals
make[3]: *** No rule to make target `/tmp/fix/s/s2/sim-7.9.50.20150415/sim/bfin/../../gdb/common/create-version.sh', needed by `version.c'.  Stop.
make[3]: Leaving directory `/tmp/fix/s/s2/o/sim/bfin'

toplevel:
	Adjust src-release.sh for sim using the gdb create-version.sh.
	* src-release.sh (tar_compress): If there's a fifth parameter,
	use that in the getver call instead of $tool.
	(sim_release): Pass gdb as fifth parameter to tar_compress.
	(SIM_SUPPORT_DIRS): Add gdb/common/create-version.sh.

i run Gentoo and then some.  tooling versions are almost never an issue (unless 
they're too new).  in this case i had a GNUmakefile in a subdir lying around 
that confused things.  not that the error maked sense:
...
make[1]: Entering directory '/usr/local/src/gnu/gdb/libiberty/testsuite'
make[1]: Nothing to be done for 'info'.
make[1]: Leaving directory '/usr/local/src/gnu/gdb/libiberty/testsuite'
make: Nothing to be done for 'info'.
make: *** No rule to make target 'info'.  Stop.

the source repos aren't going to split, so i don't think we should spend time on 
the git side.  there's no reason though we couldn't bundle version.c in the sim/ 
tree and drop gdb/ entirely.
