Hello Felix Singer, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/83313?usp=email

to look at the new patch set (#3).

Change subject: Makefile.mk: Remove bc dependency

Makefile.mk: Remove bc dependency

bc was added as dependency in commit 229e021110 ("Makefile.inc: Add left shift macro")

bc is not stated as dependency in our docs (e.g. package installation).
If you don't have bc installed you can easily get false positives on
coreboot builds. For example you build a mainboard and coreboot tells
you the build succeeded, even though you don't have bc installed.

This patch is from julius comment on CB:21601.
