[issue26926] test_io large file test failure on 32 bits Android platforms

[Xavier de Gaye]

Xavier de Gaye added the comment:

The tests are run on an ext4 file system.
test_large_file_ops does not fail on the x86_64 and arm64 (aka aarch64) Android 64 bits platforms.
test_large_file_ops still fails on x86 with the latest Android API level 24 (i.e. the latest released libc).

FWIW, the second item in https://android.googlesource.com/platform/bionic.git/#32_bit-ABI-bugs may explain why there is still no large file support on Android 32 bits platforms.
HAVE_LARGEFILE_SUPPORT cannot be used to skip the test since it is also undefined on the Android 64 bits platforms and on linux x86_64.
This new patch is not specific to Android and uses the same method as the one used in test_mmap to skip the test on platforms that do not support large files.
