bug#57109: arm-none-eabi-toolchain atomic support is broken

[Jean Pierre De Jesus DIAZ]

The following works though. No newlib or anything:

guix shell --expression='((@ (gnu packages cross-base) cross-gcc) 
"arm-none-eabi")' -- \
   bash -c "echo '#include <stdatomic.h>' \
 | arm-none-eabi-gcc -x c -o /dev/null -c -"
