new version of qpid-autotools-install script

[Jim Meyering <ji...@meyering.net>]

The previous version didn't work unless you already had the
GPG signatures of each package signer on your keyring.
Now, if the gpg signature check fails, you just get an "info:..." notice.
Later, sha1sum fingerprints are checked.

Usage: $0 [OPTION]...
Download, build, and install some tools.

Options:
 --prefix=PREFIX    install tools under specified directory
 --skip-check       do not run "make check" (this can save 50+ min)
 --help             display this help and exit

For example, to install programs into /usr/local/bin, run this command:

  $prog_name --prefix=/usr/local

If you've already verified that your system/environment can build working
versions of these tools, you can make this script complete in just a
minute or two (rather than about an hour if you let all "make check"
tests run) by invoking it like this:

  $prog_name --prefix=/usr/local --skip-check
