configure.in: cross-compile

[Dengke Du <de...@windriver.com>]

Hi all

When apr used in cross-compile, it pass 8 bytes to ac_cv_sizeof_off_t by 
the following:

     APR_CHECK_SIZEOF_EXTENDED([#include <sys/types.h>], off_t, 8)

at the line 1789 in configure.in

But when the target is x86, the apr configure as "off_t = 8", but in 
glibc the size of off_t is 4, so it maybe error, when we use the apr.h,

such as subversion.

Hopefully this is not fatal, since the byte-alignment remains a multiple of
the target platform alignment. But the converse could be quite bad.

APR_... are all custom .m4 macros and were designed with only any
attention paid to the build platform.

Patches are very warmly welcomed!
