Ah okay, I should have known.  Sorry about that.

A fourth option is to use a "bin2c" kind of build tool,
that converts a binary file into a C array that can then
be compiled into whatever you want.

Too bad.  Well not many people seem to use targets=all so there's
not much point in adding something I suppose.

Except those symbols need to have an extra underscore in the
assembler source file, with the Darwin assembler.  (Sorry I
didn't mention this earlier, I only noticed after I sent the
mail).
