This is causing the 32-bit ARM bots to fail test `tools/obj2yaml/ELF/program-headers.yaml`. It looks like an out of memory error, but it has been happening consistently for a large number of builds now, and looks related to this change.

First failing build: http://lab.llvm.org:8011/builders/clang-cmake-armv7-quick/builds/16765
