Revert "Recommit r324107."

This reverts commit r324500.

The bots found two failures:

    ThreadSanitizer-x86_64 :: Linux/pie_no_aslr.cc
    ThreadSanitizer-x86_64 :: pie_test.cc

when using gold. The issue is a limitation in gold when building pie
binaries. I will investigate how to work around it.
