How do you know it is this bug? The "final link failed: bad value"
message is pretty generic. Did you actually check that those issues no
longer appear with binutils 2.36 ?

Obviously, an annoying problem is that the BR2_BINUTILS_VERSION_2_36_X
part of the condition does not take into account external toolchains.
So for external toolchains that have binutils >= 2.36, we still won't
be able to build those packages.

But oh well, for something like OpenRISC, this is perhaps an acceptable
