Toolchain-dependent config options

Hi Masahiro,
If I copy a config with CONFIG_GCC_PLUGINS to another system which
doesn't have the gcc-plugin-devel package, it gets silently disabled by
"make olddefconfig".
I've seen multiple cases lately where this is causing confusion. I
suspect the problem is getting worse with recent added support for a
variety of toolchains and toolchain-dependent features.
Would it be possible to have an error (or at least a warning) in this
case?
For example, a "depends-error" which triggers an error if its failure
would disable a feature?
