All Linux and Android Clang ToT bots failing to link hwasan with ld.bfd internal error

Project Member Reported by r...@chromium.org, Apr 23 2018 
First failing build:
https://ci.chromium.org/buildbot/chromium.clang/ToTLinux/2197

The link error:
FAILED: lib/linux/libclang_rt.hwasan-x86_64.so 
...
/usr/bin/ld: BFD (GNU Binutils for Ubuntu) 2.24 internal error, aborting at ../../bfd/elf64-x86-64.c line 3363 in elf_x86_64_relocate_section
/usr/bin/ld: Please report this bug.
collect2: error: ld returned 1 exit status

Revision range:
good: 330459
bad:  330484

This is probably the culprit: r330474 - [HWASan] Introduce non-zero based and dynamic shadow memory (compiler-rt).

Comment 1 by alekseys@chromium.org, Apr 23 2018 

To avoid IFUNC problem, switched HWASan back fixed shadow on x86-64:
  LLVM - r330623
  compiler-rt: r330624

I guess the proper fix is to upgrade the bot to the version of binutils which has IFUNC support fixed.

Comment 2 by alekseys@chromium.org, Apr 23 2018 

r330628 adds some files forgotten in r330624
