The only two (non-toolchain) packages, gdb and dmalloc, that depends on
threads, refer to !BR2_PTHREADS_NONE.

Oh, I see what you mean:
- the prompt for the threading model is wrong when dealing with external
  toolchains: we only need to know if threads are supported or not
- a check is missing to check coherency btw external toolchain threading
  capabilties, and buildroot configuration.
