Documentation error in INSTALL notes -- location of "gmp.info"

[Will Galway]

It's been several years since I've last installed GMP, and my apologies 
if I'm doing anything dumb here (like failing to Read The Funny Manual 
;-).  In any case, I've just noticed that the INSTALL instructions for 
gmp-5.0.1 (located in the root directory of the source directory) state 
that detailed installation instructions can be found by reading the 
documentation via
      info -f ./gmp.info
or the corresponding command in emacs.  However, "gmp.info" is located 
in the ./doc directory, so this should read
      info -f ./doc/gmp.info
etc.
