When subversion run on x86 and lib32 on x86-64, it use the APR's
apr.h header file. But when configure the APR, APR meets the cross
compiling, it was hardcoded in configure.in in apr source code. As
the following:

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

It pass 8 bytes to off_t when meets cross compiling, but on x86 or lib32
the off_t in glibc was 4 bytes, so it let the application who use apr.h
go to wrong.

Such as subversion:

	svnadmin create test

So we should let the APR detect the correct off_t when cross compiling,
change it to the following:

	AC_CHECK_SIZEOF(off_t)

+Subject: [PATCH] apr: fix off_t size doesn't match in glibc when cross
+ compiling
+
+In configure.in, it contains the following:
+
+	APR_CHECK_SIZEOF_EXTENDED([#include <sys/types.h>], off_t, 8)
+
+the macro "APR_CHECK_SIZEOF_EXTENDED" was defined in build/apr_common.m4,
+it use the "AC_TRY_RUN" macro, this macro let the off_t to 8, when cross
+compiling enable.
+
+So it was hardcoded for cross compiling, we should detect it dynamic based on
+the sysroot's glibc. We change it to the following:
+
+	AC_CHECK_SIZEOF(off_t)
+
+I have send a discussing for the upstream, the maintainer said the macro in
+APR designed with only any attention paid to the build platform, considering
+cross compiling less, we can check the discussing from:
