man pages's creation broken

[Thomas Schwinge]

Hello!

Texinfo's build system's code for generating man pages (doc/Makefile.am)
is broken IMO.
Building from CVS sources I configured with '--enable-maintainer-mode'.

#v+
[...]
/bin/sh /var/tmp/build/texinfo/texinfo-4.8/missing --run help2man --name="read 
Info documents" `basename info.1 .1` >info.1
help2man: can't get `--help' info from info
make[2]: *** [info.1] Error 1
make[2]: Leaving directory `/var/tmp/build/texinfo/texinfo-4.8/doc'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/var/tmp/build/texinfo/texinfo-4.8'
make: *** [all] Error 2
#v-

I see two problems here:
* '`basename info.1 .1`' will evaluate to 'info' -- help2man will access
  'info' searching through $PATH instead of using the newly compiled
  one.  The system I was building on did not have 'info' in $PATH, so
  the build failed.
* 'info' is created as 'ginfo' (info/Makefile.am) whereas help2man is
  instructed to access 'info'.

help2man should have been called with 'help2man [...] ../info/ginfo'.
(What about cross-compilations?  ../info/ginfo might not be executable
on the building system, but that is a general problem of help2man I
suppose.)
