build: find_md5 list with mod time and sorted
It was observed that the MD5 would not change after source files had been
modified, looking deeper into the build process it was discovered that
find_md5 build function makes a list of the files being built and then
passes the list to a summing utility on stdin. The resultant MD5 is of
the file list, not the contents of the files.
The MD5 would change if the ordering of the list changed, or items were
removed or deleted.
The proposed fix is to add the modification time after the filename and
then sort the list to prevent find returning files in a different order
falsely re-triggering a rebuild. The MD5 will now change when a file is
modified or files are added/removed from the list.
Using 'T@' to show time in epoch for timezone independent behaviour.
