cc/gcc: copy file with 'cp -v', it rotates the progress bar

Installing the gcc test-suite can take a bit of time, so the
progress bar is currently not rotating because there is no
output during the copy. For an unsuspecting user, it could
mean the process hung.

With 'cp -v', the progress bar now rotates.
