Quoting David Fang <fang@csl.cornell.edu>:

Apart from parallelism, I wished the stage 2,3 compilations had a hook
for ccache-ing


Even better would be distcc, i.e. distribute the new compilers
around a cluster so you don't need to have all your cores and DIMMS
on the same motherboard to harness hugely massive parallelization.

The same hook could be used for both, it would just be a command prefixvariable, like "BOOT_CC_PREFIX".

Or you could set CCACHE_PREFIX to call distcc from ccache as well.
