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.
Fixes: fea2fed201ee5 ("riscv: Enable per-task stack canaries")
