vxworks: add target/h/wrn/coreip to the set of system include paths
In order to build crtstuff.c, I need to ensure the headers in target/h/wrn/coreip are also searched. Of course, that can be done similar to how wrn/coreip gets manually added for libgcc, e.g. by adding CRTSTUFF_T_CFLAGS += -I$(WIND_BASE)/target/h -I$(WIND_BASE)/target/h/wrn/coreip But without target/h/wrn/coreip in the default search path, all user-code that include <unistd.h> (crtstuff.c just being one such example) will have to manually add an -isystem flag adding the wrn/coreip directory: unistd.h include ioLib.h, which has #include "net/uio.h" and that header is found in target/h/wrn/coreip. In other words, the VxWorks system headers (at least for VxWorks 5.5) are written in a way that assumes wrn/coreip is in the search path, so I think it makes sense to have that by default. It will change the search order for existing setups that pass -I.../target/h/wrn/coreip (without -nostdinc), since that flag will now be ignored. I can't know whether that will break anything, but I do believe it makes sense to have the defaults actually usable without expecting all invocations to add -I/-isystem flags. From-SVN: r263689
