Remove dependency on gunzip

[Antonio Diaz Diaz]

Hello,

I recently received this error from info on a computer without the 
gunzip binary installed:
  $ info tar
  sh: gunzip: command not found
  info: Unable to find node referenced by `Tar' in `(dir)Top'.

As gunzip is a link to gzip, the only difference between using "gunzip" 
and "gzip -d" is that the former adds a gratuitous dependency on the 
gunzip name.

Could you, please, apply the attached patch whose only effect is 
partially removing the dependency of texinfo on the "gunzip" name?


Regards,
Antonio.
