The `list` command of `equery` will exit with status 3 if a package is
not found and `--quiet` is in effect. This results in some non-fatal
noise during the SDK build:

Shut the noise up. If package is not found, then there is simply
nothing to do.
Emerge flags are cryptic in general, but short flags even more so, so
expand them. While at it, I noticed some places where bash arrays
could be used, so convert those places too.
