wxmac: Multiversion support.

Some popular python packages expect to "import wxversion", which
is only available on a multiversion build.

A multiversion of wxPython should have no negative side effects.
A usual `import wx` still works.

pathname.rb: Pass -s to du instead of -d0

The option `du -s` is equivalent to `du -d0`. The former is a POSIX standard
(IEEE Std 1003.1-2008), whereas the latter is a BSD extension.

From the BSD man page:
`-s Display an entry for each specified file. (Equivalent to -d 0)`

From SUSv4:
`-s Instead of the default output, report only the total sum for each of the specified files.`

haskell-platform: don't pass environment vars to system

This isn't a bug per se, but it does cause the log filename to be 'ghc"'
rather than 'make'.
Properly escape log filename

Improve Xcode and CLT config reporting

We support three configurations: Xcode-only, CLT-only, and Xcode with
CLT. Our configuration output should correctly reflect this.

While MacOS::Xcode.version has to continue to return a guess if Xcode is
not installed in order to maintain backwards compatibility, this is an
implementation detail that we don't need to expose to the user. And it
makes `brew --config` output confusing.

So let's only print the "Xcode" line when an actual Xcode installation
is present. This makes it easy to quickly figure out which of the three
possible configurations the user is running.

Addresses #14941, more or less.
