If the user wants to know which options he has to build the
toolchain, then he will have to configre the toolchain.

It is the same with busybox, uClibc and linux. 
You can only configure  a few things from buildroot.

I think it could be harder to implement.
I do agree that you do not want a package to be totally
invisible, just because of an toolchain option.
I think that if a package IS disabled, then it could still be visible,
but the reason for it to be impossible to select is shown.

You need the information, but if you instead of:

[ ] socat

would get

--- socat -- needs toolchain with WCHAR

Would that be uncacceptable?

Maybe you could get an even better
description if each package had 
a menuconfig if the package cannot be
selected with the package name in CAPITALS.


If cyou check the box you get

--- toolchain must be built with WCHAR enabled
--- socat requires pacakge <x>

You may have to set a global variable to enable 
the reason for hiding a package.

Will complicate the Config.in files a lot, but 
would sure be nice.
It is hard searching through the Config tree help
