-Otarget + ncurses applications

[Ben Boeckel]

Hi,

I have GNUMAKEFLAGS=-Otarget in my environment because it is way more
useful to have output to have some structure. However, there is a
problem in that this breaks ncurses applications in recipes (e.g., make
menuconfig).

The way Ninja has solved this is with the "console" pool which indicates
that the rule should not run with any other rule in parallel and that it
needs exclusive access to the terminal.

Could some special rule be added to indicate that rules need these
requirements? Something like:

    .CONSOLE: menuconfig

perhaps?

It also seems that MAKE_TERMERR and MAKE_TERMOUT are kind-of lies with
-O.

Please keep me CC'd; I am not subscribed.

Thanks,
