No, I want to run different builds (for essentially the same target,
but with different sysroot trees) in parallel, using the same toolchain
binaries.

My buildsystem (briegel) runs all package builds in an minimal sysroot
tree: it first cleans the sysroot tree, unpacks the (build-time) 
sysroot tarball and then installs only the dependencies. Obviously
I cannot run multiple builds in parallel using the same sysroot dir,
since they would shoot each other ;-o

It if would be possible to specify the actual sysroot directory via
environment (eg. toolchain recognizes the $SYSROOT variable), I just
have to tweak my buildsystem to use separate sysroot dirs (eg. using
random names, etc) and properly pass them to the toolchain.
