Remove dependency on gunzip

[Antonio Diaz Diaz]

Hello,

I recently received a error message from GNU info on a computer without 
the gunzip binary installed. While fixing this error, I noticed automake 
introduces in every package using automake the same dependency that 
provoked the error in GNU info.

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 
removing the dependency of Makefile.in on the "gunzip" name?


Regards,
Antonio.
