Graphene gates a runtime check on whether it is cross-compiling, when it
should be whether it can run target binaries.

+Subject: [PATCH] build: Allow host builds when cross-compiling
+
+Environments that set up execution wrappers when cross-compiling should
+be allowed to run code. We only fall back on external properties if we
+really can't run any native code on the host machine.
