I think that if you run the "compilers" stage of build-many-glibcs.py for 
a single configuration, the resulting installed tools, if it's for a 
configuration that can run natively on the system you are using, should be 
entirely suitable for doing native build / test of glibc.

(Caveat regarding using build-many-glibcs.py on Power systems: it defaults 
parallelism to the number of CPU cores reported by the operating system, 
but some Power systems have a number of hardware threads that is much 
larger than an actual sensible level of parallelism.  So you may want to 
specify a -j option to avoid it defaulting to something like -j160.)
