lld not building with gcc

[Rafael Espíndola via llvm-commits]

I just noticed that lld is not building with gcc. The error is
peculiar. In one file it produces an undefined reference to

llvm::object::ELFFile<llvm::object::ELFType<(llvm::support::endianness)1,
false> >::uintX_t ... getVA....
In another file it gets a defined


│································
lld::elf::SymbolBody::ELFFile<llvm::object::ELFType<(llvm::support::endianness)1,
false> >::uintX_t ... getVA...

Any idea if this is a gcc bug and if so if it is easy to avoid?

Cheers,
Rafael
