Is --enable-libgomp legal with --target=avr?

[Klampiar]

Hi, I would like to know if "--enable-libgomp" configure option is legal with 
"--target=avr" architecture, becouse the build process of gcc fails at libgomp 
if both options are used. It probably doesn't make much sense to use openmp 
with such device, but I wonder if gcc with libgomp support should build OK for 
avr arch, and if not shouldn't configure script take care about this situation 
(either by ignoring --enable-libgomp option, or by exiting with error)?

Thanks in advance.
