You are getting this because configure didn't find the 'gdal-config'
script and it failed to include -lgdal.1.1 in the link arguments.  You
have to pass the full path to the gdal-config file in the --with-gdal
parameter, not just the path to GDAL (I know this can become confusing).

The configure script should have complained about this but it didn't, so
I fixed it in both 3.6.4-dev and 3.7-dev to complain about this
mistake.  The './configure --help' output also documented the option as 
'--with-gdal[=DIR]' and I changed it to '--with-gdal[=PATH]' which will
hopefully reduce the chances of confusion.

Now, you should be able to compile without getting those fixes as long
as you pass the right argument to --with-gdal:

Did you 'make install' in the GDAL directory?  That would be the best
thing to do and then you could use '--with-gdal' without any argument
assuming that /usr/local/bin/gdal-config is in your path.

If you must specify an alternate location for GDAL then you should pass
the full path and filename of the gdal-config script, if you didn't
'make install' GDAL, then the path should likely be:
  --with-gdal=../gdal-1.1.7/apps/gdal-config
