We already have bpabi.h for all ("generic") Base Platform ABI systems 
(which include bare-metal, RTOS, uClinux, SymbianOS, GNU/Linux, etc.). 
So, I think we can use eabi.h for the "bare-metal and RTOS" category. 
It's not a perfect name, but it matches existing practice in the ARM 
toolchain and elsewhere.
