commit aea89f2c1ad1cfa2ddd09fb5262f7a0616708baa
Author: Mark Wielaard <mjw@redhat.com>
Date: Mon Mar 23 15:08:27 2015 +0100
backends: aarch64 can have _GLOBAL_OFFSET_TABLE_ point anywhere in .got.
When building with relro aarch64 splits .got in a writable and read-only
part. _GLOBAL_OFFSET_TABLE_ points to the first writable symbol, not the
start of .got.
