Correct.

Those target toolchain dependencies in the host-gdb package where here
to avoid selecting a wrong version of host-gdb (which affects the
target gdb version) when the target toolchain does not have the
required feature. For example, we would allow to select 8.0 only if the
host toolchain *and* the target toolchain had C++11 support.

My PATCH 1/5 in this series is precisely here to rework that.

Everything can be simplified with less options, it's pretty obvious.
The question is whether having those options is useful :-)
