Linux/RT was a /different/ commercial real-time Linux distribution from 
TimeSys, although they may be dead now for all I know.  The name Linux-rt is 
also used for the generic real-time linux community that maintain the 
CONFIG_PREEMPT_RT patches for the kernel.org kernel.

If you're just using the standard code from Base without changing any of it 
then all you really need is to create local (SLAC-specific) aliases for the 
linux-x86 and linux-ppc targets.  In that case you can call them whatever you 
like since they don't have to make their way into the official Base release.

I would recommend that you try to avoid CPU-specific target names like 
linuxRT-ppcP2020 unless you really need them.  It is usually sufficient to 
configure gcc to build for the generic CPU family, unless you're writing 
highly tuned CPU-specific kernel-level code.  You won't want to have to 
compile everything for multiple CPU-specific architectures if all your CPUs 
can run generic linuxRT-ppc binaries instead.
