[distcc] "make install" after "make -j8 CC=distcc" still compiles entire Linux kernel

It indeed does. Search for .*.cmd files all around the place if you want
to see how the information is stored.

I personally do not use "make install" but instead "make
modules_install", which does NOT trigger a recompilation. I then copy
the kernel and associated files to /boot manually. I wonder why "make
install" and "make modules_install" behave differently WRT
recompilation.

If you want to use "make install" then I would suggest that you try
"make CC=distcc install" which would hopefully prevent recompilation.
