In newer toolchain with binutils 2.26 and GCC 5.3.0, we build binutils and GCC with machine type riscv32 and riscv64 instead of riscv. We can see it in this riscv-gnu-toolchain commit: https://github.com/riscv/riscv-gnu-toolchain/commit/dedbf07 Signed-off-by: Iru Cai <mytbk920423@gmail.com> Signed-off-by: Martin Roth <martinroth@google.com> Change-Id: Id552859ec256d80108e073d25cd51dd1fc3fbfac Reviewed-on: https://review.coreboot.org/14257 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi@google.com>
