Please give more details. What problems did you experience with `cp`
and `find`? Did this happen during a call to `make ...` for LilyPond?
This should work out of the box, which essentially means that we have
to either add tests to `configure` to catch the problematic tools, or
to rewrite the commands in the makefile or scripts to avoid issues
with GNU-style usage of those tools, for example.

Interesting. I wasn't aware that we ever call `perl` with a long list
of arguments during `make doc`.
Please repeat this with saying
```
make doc VERBOSE=1 &> make.doc.log
```
so that we can more information in the log file. Usually, such errors
can easily be circumvented by using `xargs`.
