Description of problem:
On a Rawhide x86_64 machine:
$ geos-config --clibs
-L/usr/lib@LIB_SUFFIX -lgeos_c
$ pkgconf --libs geos
-L/usr/lib -lgeos_c 

Both of them should either specify "-L/usr/lib64" or no -L flag at all.  The effects of this can be seen in the latest python-shapely build log:

+ /usr/bin/python3 setup.py build '--executable=/usr/bin/python3 -s'
cannot open shared object from 'geos-config --clibs': '-L/usr/lib@LIB_SUFFIX -lgeos_c'
there were 2 guess(es) for this path:
	/usr/lib@LIB_SUFFIX/libgeos_c.so
	/usr/lib@LIB_SUFFIX/libgeos_c.so.1

Version-Release number of selected component (if applicable):
geos-3.9.0-2.fc34.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install geos on a 64-bit Rawhide machine
2. Run "geos-config --clibs" and "pkgconf --libs geos"

Actual results:
The incorrect results shown above.

Expected results:
Correct library paths or no explicit library paths.
