Note that while the assembler change is a nice improvement, the original issue
still exists.

In the testcase that I attached before, the call to foo is now assembled to
R_X86_64_PLT32, but

        .long   foo - .

Still produces a R_X86_64_PC32 as it has to.

Since foo has default visibility, the linker could create a canonical plt entry
to be the runtime address of foo.
