Installation permissions issue with 3.0 release in Ubuntu 14.04?

Greetings,

I'm not sure where to take this issue, so I'm starting here. It's an
installation issue, not a language issue. Any tips on where to send this
would be greatly appreciated! (And of course please let me know if it's a
known issue.)

I'm one of the brave that is installing Swift 3.0 on Ubuntu 14.04 as a
system installation. I'd love to be able to take the release tarball and
simply expand it as-is to the final location in /usr.

However, there's one significant issue: many CoreFoundation files in the
archive appear to be marked with a permission of 640, which means they're
unusable by the general population on the server when installed straight
up. It's not hard to fix, but it's annoying.

Specifically, it's these files:

640 /usr/lib/swift/CoreFoundation/CFArray.h

640 /usr/lib/swift/CoreFoundation/CFAsmMacros.h

640 /usr/lib/swift/CoreFoundation/CFAttributedString.h

640 /usr/lib/swift/CoreFoundation/CoreFoundation_Prefix.h

640 /usr/lib/swift/CoreFoundation/ForFoundationOnly.h

640 /usr/lib/swift/CoreFoundation/ForSwiftFoundationOnly.h

640 /usr/lib/swift/CoreFoundation/module.modulemap

640 /usr/lib/swift/CoreFoundation/TargetConditionals.h

Note in particular that module.modulemap is locked down, which is the
source of a lovely error if users try to `import CoreFoundation`.

The rest of the archive generally uses 644 as I would expect and desire.

Can we tweak forthcoming releases to fix these permissions? Who do I have
to bug? :-)

Thanks!
