This currently doesn't work with .a files containing LLVM IR that are
not linked with -Wl,--whole-archive.
But it works for -Wl,--whole-archive, followed by .a file containing
LLVM IR, and even .a file containing regular ELF objects (like
libc_nonshared.a).

I haven't figured how to make it work with .a files w/o --whole-archive
because that requires an .a symbol table,
but ranlib is unable to emit it (it runs successfully, it justs doesn't
create the symbols).
llvm-ranlib uses an incompatible format. Perhaps it could be taught to
output ar compatible output?
