wv 1.2.9

The wv-1.2.6 version is known to crash when used with Plone to make
Word documents and others searchable. This issues was identified in
debian and they fixed by upgrading to 1.2.9-2 (the -2 is the debian
packaging version.

The initial built failed due to some incompatibility in the given
install-sh script used to install the files. This is a known issue
as evidenced by this message in the abiword mailing list:

A workaround has been implemented by creating the folders before
calling make install. This fixes the installation issue till it is
fixed upstream.

Closes #27582.

Remove obsolete DEVELOPER_DIR hacks

These days Homebrew refuses to do anything if the xcode-select path is

Stop loading a bunch of monkeypatches every time xcrun is invoked
Use a multiline conditional to make this code more readable
Delay loading Pathname until we absolutely need it
Use File.expand_path
