/etc/ld.so.conf is pretty simple:

cat ld.so.conf
include ld.so.conf.d/*.conf
/usr/kerberos/lib

/usr/local/lib


and

  ls /etc/ld.so.conf.d
mysql-i386.conf    octave-x86_64.conf  xorg-x11-i386.conf
mysql-x86_64.conf  qt-i386.conf        qt-x86_64.conf 
xorg-x11-x86_64.conf


cat /etc/ld.so.conf.d/xorg-x11-x86_64.conf
/usr/X11R6/lib64

The errors are from autotools configure tests.

I've simplified it further:

cat simple.c
   int
   main ()
   {
     return 0;
   }

gcc -o test.Xext -lXext simple.c
/usr/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status

but ldconfig does find it:

  ldconfig -v | grep Xext
         libXext.so.6 -> libXext.so.6.4
         libXext.so.6 -> libXext.so.6.4

Now, maybe this is an autotools issue, but I've rebuilt 
these src.rpms before without a hitch.

I've got a grease spot on the monitor. I'm sure it's because 
mod X is comming :)
