+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.

+Subject: [PATCH 5/7] cmake: Supporting overriding runtime libdir via
+ CLANG_LIBDIR_SUFFIX
+
+Make it possible to override the value of CLANG_LIBDIR_SUFFIX, and use
+it uniformly to control install location of runtimes (i.e. lib/clang),
+therefore supporting sharing a common runtime between multiple multilib
+variants.
+
+Previously, CLANG_LIBDIR_SUFFIX was pinned to LLVM_LIBDIR_SUFFIX
+and used only to define runtime path in driver code. This patch extends
+its use to building and installing the runtime (the former is needed for
+tests to work correctly).
+
+The goal is to support install layout alike "LLVM_LIBDIR_SUFFIX=64
+CLANG_LIBDIR_SUFFIX=''" -- where all shared libraries would be installed
+into ABI-specific /usr/lib64, while runtime (that is common between
+multilib ABIs) would be installed into /usr/lib.
