[swift-dev] Issues when building swift using GNU 2.26 related to protected symbols

I was running some tests using newer GNU ld, and I hit this issue:

/usr/bin/ld: stdlib/public/core/linux/x86_64/Swift.o: relocation
R_X86_64_PC32 against protected symbol
`_Tvs19_emptyStringStorageVs6UInt32' can not be used when making a
shared object

I could work around that issue by moving the definition into a C++
file, but that didn't get me far -- I got the same error, but about
'_TMPSa' (generic type metadata pattern for Swift.Array).

Does it seem like a bug in LLVM codegen or another bug in GNU ld that
was introduced recently?

This issue will prevent Swift from compiling on Ubuntu 16.04 or a recent Debian.
