I updated my ARM GCC toolchain from 10.3 to 11.3 and noticed a build failure.
```
misc/lib_impure.c:48:8: error: token "@" is not valid in preprocessor
expressions
48 | # if (__NEWLIB__ < 4 || __NEWLIB__ == 4 && __NEWLIB_MINOR__ < 2)
| ^~~~~~~~~~
make[1]: *** [Makefile:135: bin//lib_impure.o] Error 1
make[1]: Leaving directory '/Users/mike/Code/nuttx-workspace/nuttx/libs/libc'
make: *** [tools/LibTargets.mk:174: libs/libc/libc.a] Error 2
```
This is with the NuttX 12.0 release. The 10.3 toolchain builds fine.
New: `arm-none-eabi-gcc (Arm GNU Toolchain 11.3.Rel1) 11.3.1 20220712`
Old: `arm-none-eabi-gcc (GNU Arm Embedded Toolchain 10.3-2021.10) 10.3.1
