kernel: Set CONFIG_FRAME_WARN depending on target

Browse Source 
This set the CONFIG_FRAME_WARN option depending on some target settings.
It will use the default from the upstream kernel and not the hard coded
value of 1024 now.

Tell the compiler to warn at build time for stack frames larger than this.
Setting this too low will cause a lot of warnings.
Setting it to 0 disables the warning.
