Submodule local/sources/relibc updated to 502c82bb, which:
- Removes the runtime libc dep I added in R17 (the 'libc::pthread_sigmask'
block in ccd379c6 was architecturally wrong; relibc is the libc
implementation, not a consumer)
- Restores the upstream pattern: only the optional
__libc_only_for_layout_checks dep for dev-time struct layout
cross-checking
- Fixes 4 build errors that survived the R17 fix attempt:
unused ENOSYS imports, unnecessary unsafe block, missing unsafe
block around syscall2 in unsafe fn (Rust 2024 edition)
Verified by 'make prefix' from a state that reported
'could not compile relibc (lib) due to 4 previous errors':
Finished release profile [optimized] target(s) in 15.94s
[sysroot] synced relibc to redoxer toolchain
relibc now builds clean end-to-end without depending on the libc
crate at runtime. Matches upstream Redox relibc's no-libc
architecture.
