Currently, the generic libsbi.a is compiled in create-binary-archive.sh before platform specific firmwares so a libsbi.a without any SBI extension gets linked to the platform specific firmwares. To address this, remove the temporary build directory in create-binary-archive.sh before using it. Signed-off-by: Anup Patel <apatel@ventanamicro.com>
