[Buildroot] [git commit] Add 'bc' in the mandatory dependencies

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=7cbebbc48c26ddfb18da23ffba356744a5592ea6
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since a few kernel releases, having 'bc' installed is mandatory to
build the kernel. See commit
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=70730bca1331fc50c3caacaea00439de1325bd6e
of the kernel.

Since this tool is generally available by default in distributions,
and we're unlikely to see version-specific problems with it, we
just check for it to be installed in
support/dependencies/dependencies.sh.
