add a -I to find the included ltdl.h (vs. a system-installed ltdl.h) - Clean up kruft in a bunch of Makefile.am's to remove now-unnecessary AM_CPPFLAGS settings to get static-components.h for each framework - Move the component_repository API functions out of opal/mca/base/base.h and into opal/mca/base/mca_base_component_repository.h in order to decrease unnecessary dependencies (e.g., before this, almost everything in the tree depended on ltdl.h, which is unnecessary -- only a small number of files really need ltdl.h) This commit was SVN r7127.
