Brian Barrett b8442ba505 Revamp the handling of wrapper compiler flags. The user flags, main configure
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.

This commit was SVN r27950.
