It seems that using the external linker somehow causes objdump to only dump instructions
associated with exported symbols.

Comment 1:

Can reproduce on Linux, not on Mac.
In GNU nm, looks like symbols in the failing binary are 't' not 'T'.
go tool objdump is clearly ignoring those.
go tool nm lists them fine.
I suspect once I finish hooking up objdump to the new internal/objfile package, it will
just work.
