Reproduction tarball for negative size problem
Trying to build one of FreeBSD's boot loader components with lld 10.0.0, we see
the following error appear:
$ ld.lld
--sysroot=/usr/obj/share/dim/src/freebsd/clang1000-import/amd64.amd64/tmp
--eh-frame-hdr -Bstatic -m elf_i386_fbsd -o loader_lua.sym

18446744073707016908 = 0xffffffffffd952cc, so it is pretty clear that lld is
somehow creating a negative size.
Bisecting shows that this was introduced with <a href="https://reviews.llvm.org/rL371957">https://reviews.llvm.org/rL371957</a>
("[ELF] Map the ELF header at imageBase"). It seems that this change has a bad
effect when both -Ttext 0x0 and --no-rosegment are used.</pre>
