Fix prelink build with automake-1.13

Fix prelink build with automake-1.13

[Marko Lindqvist]

[PATCH] fix build with automake-1.13.

Long obsolete AM_CONFIG_HEADER is completely removed from automake-1.13,
which errors out upon seeing it.
configure.in -> configure.ac rename is not strictly necessary yet,
use of deprecated name still gives only warning.

Problem in dropping obsolete constructs is that support for autotools
versions so ancient that now-obsolete way is the only way to do things.
configure.in seems to have AC_PREREQ(2.13), but with these changes
(if not earlier) such an ancient autoconf will not do.

[PATCH] fix build with automake-1.13.

[Marko Lindqvist]

Rename autoconf input file from deprecated name configure.in to
configure.ac
Replace AM_CONFIG_HEADER obsoleted in automake-1.13 with
AC_CONFIG_HEADERS.

Do you know if the change to AC_CONFIG_HEADER (from AM_CONFIG_HEADER) is 
supported in autoconf 2.13?  Assuming it likely is, I'll get this merged. 
Otherwise we should expect to bump the AC_PREREQ.

BTW I'll check and see if this patch is specific to the cross-prelinker or 
applicable to the upstream prelink as well.  Seems like if it's applicable there 
they may want it as well..

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.
