Responding to my own query.  I just checked and the cross-prelinker is already 
setup for AC_PREREQ(2.50):

http://git.yoctoproject.org/cgit/cgit.cgi/prelink-cross/tree/trunk/configure.in?h=cross_prelink

(The unmodified upstream -- master branch -- is still using AC_PREREQ(2.13). 
But we don't use that in OE/Yocto Project work.)

The -- cross_prelink branch -- does still have the AM_CONFIG_HEADER.  I'll get 
that updated.  I will also rename the configure.in to configure.ac and adjust 
anything else that references that.
