Detect: Recognize framework include directories on OS X

Some OS X compilers report their framework include directories with an
explicit suffix in "-v" output.  Others report without an explicit
suffix but the paths imply they are for frameworks by ending in
"/Frameworks".  Recognize either suffix and remove the explicit suffix.
Add framework directories with "-iframework" instead of "-isystem".
