This is almost exactly what I'm doing (I have localhost at the front).
The problem is, that unless -jN (for N > 1) is specified, this
configuration is worthless - you would be better not using distcc at
This is because distcc round-robins through the host list from the
start each time, passing over a host only if it has exceeded its
job limit. As -j1 (or no -j option) will only ever cause one job to
be running at once, only the first host will ever be used.
Ergo, unless -jN (N > 1) is given, *the use of distcc is a complete
waste of time* (except in a few very special cases).
I'm rather inclined to submit a PR on the matter, as it shouldn't
be that difficult to a create a variable (say, PKG_MAKEFLAGS) to
pass flags to the make invocation in the package's build stage.
What does everyone think?
