master 7fb0248a33d: Port to the Android NDK r10b

[Po Lu]

branch: master
commit 7fb0248a33dc721ae570c294b04f6da94cd96b10
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Port to the Android NDK r10b
    
    * src/androidvfs.c (android_saf_stat, android_saf_file_open)
    (android_fstat): Eschew accessing POSIX timespec fields in
    struct stat, employing accessors supplied in Gnulib stat-time.h
    in their place.
