devel/lld: import lld-7.0.1
LLD is a linker from the LLVM project that is a drop-in replacement for system
linkers and runs much faster than them. It also provides features that are
useful for toolchain developers.

+LLD is a linker from the LLVM project that is a drop-in replacement for system
+linkers and runs much faster than them. It also provides features that are
+useful for toolchain developers.
+
+The linker supports ELF (Unix), PE/COFF (Windows), Mach-O (macOS) and
+WebAssembly in descending order of completeness. Internally, LLD consists of
+several different linkers. The ELF port is the one that will be described in
+this document. The PE/COFF port is complete, including Windows debug info (PDB)
+support. The WebAssembly port is still a work in progress (See WebAssembly lld
+port). The Mach-O port is built based on a different architecture than
+the others. For the details about Mach-O, please read ATOM-based lld.
