In my case, it seems to be 64 bit:

Non-fat file: /tmp/httpd-trunk/lib/libapr- is architecture: x86_64

Check the effect of the compiler flags you're passing. CFLAGS is in theory set externally
to configure.

The Universal Binary concept definitely covers 32/64 bit code, and this scenario is supported
by APR. From include/apr.h:

 * Darwin 10's default compiler (gcc42) builds for both 64 and
 * 32 bit architectures unless specifically told not to.
 * In those cases, we need to override types depending on how
 * we're being built at compile time.
 * NOTE: This is an ugly work-around for Darwin's
 * concept of universal binaries, a single package
 * (executable, lib, etc...) which contains both 32
 * and 64 bit versions. The issue is that if APR is
 * built universally, if something else is compiled
 * against it, some bit sizes will depend on whether
 * it is 32 or 64 bit. This is determined by the __LP64__
 * flag. Since we need to support both, we have to
 * handle OS X unqiuely.
#ifdef DARWIN_10

Is the DARWIN_10 symbol present on your platform?
