+Subject: [PATCH 3/7] driver: Support checking for rlimits via cmake (when
+ bootstrapping)
+
+Add a cmake check for sys/resource.h and replace the __has_include()
+check with its result, in order to make it possible to use rlimits when
+building with compilers not supporting __has_include() -- i.e. when
+bootstrapping.
+
+Patch: https://reviews.llvm.org/D23744
