And we should be aiming to make the GCC build, test and install process 
simpler: install to a staging directory during build, use the built-in 
relocatability in building target libraries and running testsuites rather 
than needing to pass long sequences of -B etc. options at those stages, 
and just copy the staging directory for final installation.  (It's nasty 
that not just the build systems of the various toolchain components but 
upstream DejaGnu itself has hardcoded information about how bits of the 
tools can locate each other in their build directories.  Nothing should 
ever need to know that; the staging install code should just put things so 
that they can find each other automatically.)
