I was looking at making static pattern rules to divert host objects to a 
host rule, with separate object lists for files that want pedantic and 
non-pedantic (leaving the current set of individual file rules would 
cause conflicts).

It seems that nothing in tools/Makefile is using -pedantic or any of the 
other HOSTCFLAGS set in tools/Makefile; HOSTCFLAGS is getting 
overwritten by config.mk.  It looks like maybe this was introduced when 
HOST_CFLAGS was changed to HOSTCFLAGS.

Any thoughts on how to untangle things?  What flags to we really want to 
use here?  Given the number of files that have been exempted, do we 
still want to keep the -pedantic stuff around?
