IIRC target/linux/install does two things:

1) Prepares kernel parts of image for each selected profile (that is 
uImage for those that use uImage, embed commandline, etc)

2) Builds the actual images, when image building is selected

In reality the real time-waster is building a huge number of unwanted 
kernel image parts and/or images.

I think think for this part, the lowest cost path is find a way to 
select only wanted images, for #of images/kernel parts > 1.

Basically, if there is a way to do checkboxes instead of a radio list in 
profile selection, that would solve the issue IMO.

target/linux/compile is still somewhat annoying, but it's the lesser of 
the issues and probably a harder problem to solve in a robust way.
