This patch looks for LIBMPI_* kinds of flags in the post_configure.sh

script in components and distributes them as appropriate throughout
the tree (previously, we only did WRAPPERS_* flags).  These flags are
*only* used when libmpi is being build statically (--disable-shared
--enable-static).

I also added another classification of flags -- LIBMPI_ALWAYS_* and
WRAPPERS_ALWAYS_* for flags that should always be added to the libmpi
/ wrapper linker lines, not just when compiling libmpi statically.

This commit was SVN r4322.
