how to share just the host tools among different builds?

how to share just the host tools among different builds?

[Robert P. J. Day]

  i'm drawing a blank at the moment so this might be a trivial
question -- is there a way to share the non-toolchain, host tools
across different builds on my development host?

  if i'm doing closely-related builds (or even for totally different
architectures), i can see the host tools that are built under
tmp/sysroots/x86_64-linux/... and one would think that, theoretically,
those tools are appropriate for all sorts of independent builds, even
if the toolchain is different.

  is there a simple setting that allows me to take advantage of all
those host tools that were built during an initial build, and continue
to use them in subsequent builds?

Its called sstate ;-).

Just share the native parts between the builds. They're usually in a
distro specific directory.

Cheers,

  i suspected it was sstate-related, just wanted to be sure i could be
that specific. will go back to reading now ...
