AFAIK avr-rtems compiler does not use avr-libc, but uses newlib. I
talked previously with Joel Sherrill (CC), who is in charge of RTEMS,
about the possibility of them using avr-libc, but he declined the offer
because (IIRC) the RTEMS project uses newlib extensively as RTEMS is
POSIX oriented.
And detecting the avr32-gcc compiler for avr-libc is not correct either.
AVR32 currently uses Newlib also. But there has been some work (awhile
ago now) on the possibility of doing an avr32-libc project specifically
for the avr32 target.
