File Makefile.inc:

https://review.coreboot.org/#/c/21601/1/Makefile.inc@138
PS1, Line 138: int-shift-left=$(shell echo "$(call _toint,$(word 1, $1)) * (2 ^ $(call _toint,$(word 2, $1)))" | bc)
Why not just use shell inline computation like the others, e.g.:

$(shell expr $(call _toint,$(word 1, $1)) << $(call _toint,$(word 2, $1)))

I don't think we have a dependency on bc yet, no reason to add one.
