Pass -C default-linker-libraries to rustc
By default, rustc passes -nodefaultlibs to the linker. In some cases,
this can cause compiler builtins (e.g. __cpu_model, used by
__builtin_cpu_supports) not to be linked in:
= note: /nix/store/s2cjhni3s6shh0n35ay1hpj8d85k44qk-x86_64-unknown-linux-musl-binutils-2.43.1/bin/x86_64-unknown-linux-musl-ld: ./libbcachefs.a(tools-util.o): in function `resolve_crc32c':
/build/source/c_src/tools-util.c:457:(.text+0x1023): undefined reference to `__cpu_model'
collect2: error: ld returned 1 exit status
I saw this with static musl GCC builds, and others have reported it with
Clang.
