Since commit v3.1.0-rc1~564^2 (OS X: Use -iframework for system
framework directories, 2014-05-05) we test the version of Clang is smaller
that 3.1 to see if it supports -iframework.

Considering that "iframework" support has been added in clang@r142418
(Frontend: Support -iframework.) prior to clang 3.1, this made sense.

That said, considering that support for multiple -iframework parameters
has been added later in clang@r164607 (-iframework should allow separate
arguments. ) prior to clang 3.2, this commit updates the check to enable
framework support only if version is >= 3.2
