Subject: [PATCH] scripts/sorttable: riscv: fix undelcred identifier 'EM_RISCV' error

Fix the following build break by adding a conditional definition
of EM_RISCV in order to allow cross-compilation on machines
which do not have EM_RISCV definition in their host.

build break log from [1]:
scripts/sorttable.c:352:7: error: use of undeclared identifier 'EM_RISCV'
