[Buildroot] [PATCH 2/3] toolchain/toolchain-wrapper: use Gcc bug 97208 instead of repeating it

[Giulio Benetti]

Now that we have added Gcc bug 97208 we can use it instead of repeating it.
So let's substitute bug condition with bug presence. Also note that gcc bug
97208 is still present in gcc 11.1.0 so better to make comment more generic
and keep a detailed description in toolchain/Config.in
