Maintains the type signature of the existing matchpathcon_filespec_add() entry point on 32-bit archs but maps the API to a new matchpathcon_filespec_add64() entry point that takes a 64-bit ino_t argument instead. Software on 32-bit Linux ports which historically use a 32-bit time_t (thus affected by the y2038 problem) have, as a precondition of migrating to 64-bit time_t, that they also migrate to large filesystem support because glibc does not provide entry points for the cross-product of (LFS: yes, LFS: no) x (time_t: 32, time_t: 64). In order to support smooth migration of such operating systems from 32-bit time_t to 64-bit time_t, it is useful for libselinux to: - provide entry points on 32-bit systems for both LFS and non-LFS variants of the API (as glibc itself does) - use LFS internally for all filesystem calls (just in case) - map the API call to the correct implementation based on the build environment of the caller.
