<pre>When building clang/llvm on aarch64-linux, using a clang compiler, the
following error is produced:
/usr/bin/ld: lib/libLLVMSupport.a(PrettyStackTrace.cpp.o): unrecognized
relocation (0x20c) in section `.text._ZN4llvm21PrettyStackTraceEntryC2Ev'
/usr/bin/ld: final link failed: Bad value
clang-3.7: error: linker command failed with exit code 1 (use -v to see
invocation)
This is because llvm recently started making use of a thread_local variable in
PrettyStackTrace.cpp, and the AArch64 backend in llvm produces TLS relocations
that are not supported by gnu ld.bfd.</pre>
