So, I don't understand what your patch brings: what you describe in your commit log is already possible today. The following defconfig is already possible with Buildroot today: BR2_arcle=y BR2_archs38=y BR2_TOOLCHAIN_BUILDROOT_GLIBC=y BR2_BINUTILS_VERSION_2_33_X=y BR2_GCC_VERSION_9_X=y It builds an ARC HS38 glibc toolchain with upstream gcc 9.x and upstream binutils 2.33.
