of course having such a setup is preferable.
however i have to build sabotage as a whole, and am testing different 
compilers
that are not necessarily able to compile using distcc with an 
identically built cross-compiler.
engineering such an environment, that is even embeddable into the 
sabotage build environment,
seems like a herculean effort.

also it doesn't solve the problem that you simply don't want to have the 
math library, if it
for example breaks pcc.

it takes a pretty long time, especially when built with .a and .so support.
for example, to compile the things in stage0, you don't need math 
support at all, and the full musl
gets built in stage1 again.
if i can halve the time spent during stage0 musl builds, that will sum 
up soon.
