Currently, rustc defaults to invoking `cc`, even if `HOSTCC` is defined, resulting in build failures in hermetic environments where `cc` does not exist. This includes both hostprogs and proc-macros. Since we are setting the linker to `HOSTCC`, we set the linker flavor to `gcc` explicitly. The linker-flavor selects both which linker to search for if the linker is unset, and which kind of linker flags to pass. Without this flag, `rustc` would attempt to determine which flags to pass based on the name of the binary passed as `HOSTCC`. `gcc` is the name of the linker-flavor used by `rustc` for all C compilers, including both `gcc` and `clang`.

Psst, next time I'd recommend putting patch version to version changes here. Still, LGTM.
