gen-build.py only appears to generate source dependencies for 
MODULE/ARCH/*.c and I have them in file_io/unix/xattr/SUBARCH.c

eg contents of build-output.mk:

file_io/unix/xattr.lo: file_io/unix/xattr.c .make.dirs include/apr.h 
include/apr_general.h include/apr_errno.h include/apr_inherit.h 
include/apr_file_info.h include/apr_user.h include/apr_file_io.h 
include/apr_allocator.h include/apr_want.h include/apr_thread_mutex.h 
include/apr_pools.h include/apr_time.h include/apr_file_xattr.h 
OBJECTS_file_io_unix = file_io/unix/filepath.lo file_io/unix/seek.lo 
file_io/unix/buffer.lo file_io/unix/dir.lo file_io/unix/filepath_util.lo 
file_io/unix/copy.lo file_io/unix/tempdir.lo file_io/unix/mktemp.lo 
file_io/unix/filedup.lo file_io/unix/pipe.lo file_io/unix/flock.lo 
file_io/unix/filestat.lo file_io/unix/xattr.lo file_io/unix/readwrite.lo 
file_io/unix/fileacc.lo file_io/unix/fullrw.lo file_io/unix/open.lo

is missing file_io/unix/xattr/solaris.c, file_io/unix/xattr/linux.c, etc

So modifying an implementation doesn't trigger a rebuild of xattr.lo
