This argument is definitely true for someone wanting to compile a
kernely. To what extent, however, does this affect the generation of
toolchains? In other words, does the toolchain, libc most likely,
depend on specific CONFIG_* options, and if so, which?

Maybe it would be a good idea to start collecting such critical CONFIG
switches on a per-arch basis, what do you think?

For completeness, besides the linux/autoconf.h file a toolchain also
requires linux/version.h. Obviously this is an arch invariant, though.
In addition, the include/asm link is needed.
