[Buildroot] [git commit] dependencies: test all programs before bailing out

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=11f4c694e97f9610148b043f1c4119af047dba6a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The current dependencies code abort as soon as one program is
missing. It is quite annoying when multiple programs are
missing. Instead, bail out if needed after testing all programs.
