Summary:                    apr_memcache test use file-based test to detect
library availability
Description: 
As the test hardcode the location of the file to be $prefix + lib, it fails
for x86_64 biarch hosts, where libs are in $prefix + lib64. It is generally
recommended to never use physical test for libs presence, only compilation
tests, so as to be as most platform-independant as possible.

Attached patch fix the issue, turning the original unique prefix option to
three, allowing to specify either prefix, libs or include path for
apr_memcached. I just realize it would have been even better to just use
$libdir and $includedir if neither option was given.

I also tried to test apr_memcache header, using AC_CHECK_header, but it
failed for syntax errors in apr headers. Given my lack of knowledge of
this specific part, I did not succeed.
