flags, and mca flags are kept seperate until the very end. The main configure
wrapper flags should now be modified by using the OPAL_WRAPPER_FLAGS_ADD
macro. MCA components should either let <framework>_<component>_{LIBS,LDFLAGS}
be copied over OR set <framework>_<component>_WRAPPER_EXTRA_{LIBS,LDFLAGS}.
The situations in which WRAPPER CPPFLAGS can be set by MCA components was
made very small to match the one use case where it makes sense.
