+// RISCV-NOT:  unsupported option '-fno-emulated-tls' for target 'riscv64-unknown-linux-android'
+// RISCV-ERROR:  unsupported option '-femulated-tls' for target 'riscv64-unknown-linux-android'

Prepend `error:`

For the `NOT` pattern, use `RISCV-NOT: error:` or change FileCheck to `FileCheck --implicit-check-not=error:`
