I hit this exact same error on my Mac M1. It looks like the psximfs03 test is too big for the default ERC32 memory map, so the linker fails.

If you just need the toolchain and samples (like Hello World) to work, you can turn off the full test suite in config.ini. This worked for me:

> \[sparc/erc32\] 
>
> RTEMS_POSIX_API = True 
>
> BUILD_TESTS = False 
>
> BUILD_SAMPLES = True

With this, ./waf finished successfully and I could run hello.exe on the simulator.
