pie: Don't forget to include sub-text sections into the blob
pie: Don't forget to include sub-text sections into the blob

I've just got an interesting built problem which I never saw
before (and which I can't reporoduce at moment):

 | `.text.unlikely' referenced in section `.text' of parasite.o: defined in discarded section `.text.unlikely' of parasite.o

Including sub-text sections is a good thing anyway.
