If TCLIBC='baremetal' is set in local.conf, nativesdk-libstd-rs build fails
with:
| error[E0412]: cannot find type `c_char` in the crate root
| -->
/usr/src/debug/libstd-rs/1.75.0/rustc-1.75.0-src/vendor/libc/src/unix/mod.rs:56:29
| |
| 6 | pub type c_schar = i8;
| | ---------------------- similarly named type alias `c_schar` defined here
| ...
| 56 | pub gr_name: *mut ::c_char,
| | ^^^^^^
This happens because rust_gen_target() sets os="none" when TCLIBC is
'baremetal' - even for nativesdk targets. However, nativesdk packages are
built against glibc, so the correct 'os' value should be "linux".
Fix this by setting the os field based on {TARGET,HOST,BUILD}_OS variables,
as it is already done in rust_base_triple(), instead of relying on TCLIBC.
