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. Signed-off-by: Matthew Maurer <mmaurer@xxxxxxxxxx> --- Updated the patch to reflect Nick's comment that KBUILD_HOSTLDFLAGS should be respected as well. I did not switch it to use HOSTLD for two reasons: * That variable is not globally defined - it is only available in two subdirectories of tools/ * C host scripts are linked by HOSTCC as well, even when linking a collection of object files. It *prints* HOSTLD, but invokes HOSTCC. See scripts/Makefile.host cmd_host-cmulti for an example. [...]
