+From: Alberto Garcia <berto@igalia.com>
+Description: Use WTF_CPU_UNKNOWN when building for riscv64
+ WebKitGTK doesn't build on riscv64 even with the JIT disabled.
+ Treating the CPU as unknown is perhaps a bit severe, but it allows us
+ to get the build done until someone steps up to maintain this
+ properly.
