There is a problem with your machine.  By default, pkg-config looks at 
/usr/lib/pkgconfig, there is no need to tell it so.

From man pkg-config:
       pkg-config retrieves information about packages from special 
metadata files. These files are
       named  after  the  package,  and  has a .pc extension.  On most 
systems, pkg-config looks in
       /usr/lib/pkgconfig, /usr/share/pkgconfig, 
/usr/local/lib/pkgconfig and /usr/local/share/pkg‐
       config for these files.  It will additionally look in the 
colon-separated (on Windows, semi‐
       colon-separated) list of directories specified by the 
PKG_CONFIG_PATH environment variable.

Since with PKG_CONFIG_PATH=/usr/lib/pkgconfig ./configure it works, it 
means that on your system pkg-config does not look in 
/usr/lib/pkgconfig, so it was somewhat wrongly installed.
