Added LFS_CONFIG for user provided configuration of the utils
Suggested by sn00pster, LFS_CONFIG is an opt-in user provided
configuration file that will override the util implementation in
lfs_util.h. This is useful for allowing system-specific overrides
without needing to rely on git merges or other forms of patching
for updates.
