Possibility to build more kernels in one shot?

Possibility to build more kernels in one shot?

[CIJOML]

Hello,

currently I compile kernel for 12 different machines. I would like to see 
profile support in kernel, so I could have all my .configs in source and 
compile them in one shot. and than see in profile directory subdirectories 
for every config with it's vmlinuz and modules.

I think it would speedup also compilation time because some .o should be than 
reuse.

Thanks a lot for reply

Michal

Write a script, shouldn't take more than 15 min including testing.
And use "make O=".

Very optimistic hope. Use ccache(1) if you want .o reuse.

I currently use it, but It is not a good idea (fill make oldconfig 12x
with mostly same answers makes me personally mad)
