[QBS] qbs.targetOS property

[William Gallafent]

Hi all,

Coming back to QBS after a break, I found that some of my checks for
“qbs.targetOS” were no longer working … because “mac” which I was
previously using has become “osx” in the current version (1.2.1).

When I consulted the documentation at
http://qt-project.org/doc/qbs-1.2/qbs-module.html#targetos I noticed
that the list of possible values for target OS is not sorted
alphabetically, which seems a bit odd! Anyway, just thought I'd not
this change in the list for the sake of the archive in case anybody
else hits the same problem.
