Update meta mode makefiles
meta2deps - add checks to detect truncated/corrupted filemon data
(only known to happen on Linux hosts), to ensure we do not auto
update dependencies based on incomplete data.
meta.stage.mk adds STAGE_SHLIB_LINKS_FILTER and STAGE_LINK_AS_*
We also allow for hosts where egrep is deprecated for grep -E
