Tools: Checksum for gcc-arm download on arch prereqs 

This will check to see if the tar.bz2 file exists and if it does it will
run a checksum and skip redownloading the file if its already there. If
the checksum fails or the file doesn't exist it will redownload the
file.

I ran into issues with the download taking so long that my sudo
permissions timed out and the install failed to complete. When rerunning
the script it would redownload the file even if the file was already
there. This change solves this issue.
