We don't have M1/M2 Mac to try this patch, the fix base on the link error:
```
ld: warning: pointer not aligned at address 0x10006C5D2 ('_g_tcbinfo' + 18
from nuttx.rel)
ld: unaligned pointer(s) for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
```
18 is the offset of reg_off field in old tcbinfo_s. With this patch, the
offset change to 16 which should satisfy the alignment requirement.
