To fix the bug, probably.

But one question: For the time being, can you work around the bug by
making the symbol global? If I modify your test case to include

module asm ".global foo"

llvm-nm will print

---------------- T _start
                 U foo
---------------- T foo

Which looks silly, but will work since the linker will resolve "U foo"
to "T foo".
