FWIW, the MSVC build ends up writing the list of object files to a temp
file and then having the linker read that list. (This is all done behind
the scenes though, it's not something we made up) IIRC the gcc linker can
also take the commandline from a file instead of the actual commandline,
which should be workable I think.
