I have a proposal for a solution:
Use the 'sum' utility like in

sum -r src/functions/*/* | cut -d' ' -f1,8i

Probably we need to test whether the '-r' flag is required/supported
in configure.

This has the added advantage of resisting to timestamp breakage.

Eventually we could ship a small C program and compile it to do
this task in a more portable way.
