Description Tilman Keskinöz 2013-02-25 15:29:15 UTC 
support/dependencies.sh requires that bison is installed on the host system.

This is unnecessary for packages that use bison, because buildroot supports to depend on a host-bison.

The only other usage is in the kconfig build, but kconfig builds successfully without bison before dependencies.sh is run. 

Suggested solution:
Remove bison from support/dependencies.sh

I agree, but I think bison on the host might be needed for the internal toolchain backend, while building binutils/gcc/gdb. We would need to check that, and add the needed dependency on host-bison where needed.
