gcc13 was still being built despite gcc-native/rust-native being deferred, and it failed the whole build: binutils-native pulled it transitively. It is the same dependency pattern already removed from gcc-native -- what the recipe actually needs is a cross compiler, and that comes from the prefix toolchain on PATH (x86_64-unknown-redox-gcc, now 16.1.0), not from a cooked gcc13 package. Keeping it meant building GCC 13 with GCC 16, which does not work: the host link fails with the libstdc++ 128-bit float helpers unresolved (__eqtf2/__getf2/__gttf2/__letf2/__unordtf2 against /usr/lib/gcc/x86_64-pc-linux-gnu/16/libstdc++.so), a host/target libgcc leak, and beyond that GCC 16 ICEs on GCC 13's libsupc++. See local/docs/NATIVE-TOOLCHAIN-WORKSTREAM.md. binutils-native cooks clean without it.
