I compared the man pages of g++ and ppuxlc++ and tried to narrow down what
the problem may be. ppuxlc++ does not have -MT, -MD nor -MP (-MF appears to
be their catchall where g++ has finer grained control on this, if I
understood it correctly). If I simply remove those I get .lo and .o files.
ppuxlc++ also has a qmakedep=gcc option which I don't really understand the
purpose of. So I guess the question now is how do I conditionally specify
the arguments so that the unrecognized options are not supplied to libtool?

Thanks.
