------- Additional Comments from Landry Breuil <landry at openbsd.org>
https://bugs.webkit.org/show_bug.cgi?id=109246 splitted stuff from configure.ac
to Source/autotools.

As it is now, it doesnt build on hosts where sh is not bash, because it uses
a+="foo" constructs which are not valid in posix shells.

$a+="bar"
ksh: a+=bar: not found
