libstdc++: Fix testsuite for remote testing (and sim)

The problem here is that v3_additional_files will have a space
at the begining of the string as dg-additional-files will append
`" " $files` to it.  Then when split is called on that string,
there will be an empty file and copying a dir will just fail for
remote/sim testing (I didn't look at why it works for native
testing though).

Ran a full libstdc++ testsuite using a sim board for testing.

libstdc++-v3/ChangeLog:

	* testsuite/lib/libstdc++.exp (v3_target_compile): Call
	string trim on v3_target_compile before calling split.
