xmount: fix URL

Fixes #31053.
brew.1: reference GCC 4.9.
gcc: provide version_suffix class method.
git-annex: use gcc version_suffix class method.
OS::Mac: allow clearing compiler version cache.

Without this it’s impossible for brew-test-bot to be able to verify if
installing GCC has allowed it to fix a compiler selection failure.
brew-test-bot: clear compiler version cache.

This fix means that brew-test-bot can bottle formulae that require GCC
again.

plt-racket: use source distribution.

A source distribution for a release is configured with a suitable
package catalog, which avoids the problem reported as Racket PR 14648
(query at http://bugs.racket-lang.org/).

Using the "builtpkgs" variant of the source distribution makes the
installation work with pre-built packages, which enables faster installs
of Racket packages.
