Guenter Roeck 1897993bb8 riscv: Disable STACKPROTECTOR_PER_TASK if GCC_PLUGIN_RANDSTRUCT is enabled ...

commit a18b14d8886614b3c7d290c4cfc33389822b0535 upstream.

riscv uses the value of TSK_STACK_CANARY to set
stack-protector-guard-offset. With GCC_PLUGIN_RANDSTRUCT enabled, that
value is non-deterministic, and with riscv:allmodconfig often results
in build errors such as

cc1: error: '8120' is not a valid offset in '-mstack-protector-guard-offset='

Enable STACKPROTECTOR_PER_TASK only if GCC_PLUGIN_RANDSTRUCT is disabled
to fix the problem.
