Arm GNU toolchain version greater than 11.2 will throw out warnings during linking, such as
```
closer.c:(.text._close_r+0xc): warning: _close is not implemented and will always fail
lseekr.c:(.text._lseek_r+0x10): warning: _lseek is not implemented and will always fail
readr.c:(.text._read_r+0x10): warning: _read is not implemented and will always fail
```
These link warnings will terminate build.
According to Arm GNU toolchain developers, developers are expected to provide all system calls implementation when using `nosys.specs` in new Arm GNU toolchain version.
TF-M is working on to workaround this issue via https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/20612.
