Internal linking is currently enabled by a separate command-line 
flag; we still use the system linker by default (just as a 
precaution to avoid needless breakage because of a new feature).

lld works for COFF, ELF as well as Mach-O. For the latter, there 
is the problem of locating the appropriate C runtime libraries to 
consider, though (those that the `gcc` linker driver implicitly 
passes to the underlying `ld`).

Yes, that should work. As far as I know, it doesn't support OMF, 
though, so we would need to find COFF C/system libraries we can 
redistribute - it is unclear whether Microsoft's license allows 
redistribution of their static libraries.
