cmd/objdump: does not provide file/line info for files built with -buildmode=pie #17883
Description
go build -buildmode=pie ~/hello.go
go tool objdump -s 'main.main' hello
Observe that the file/line information is shown as just :0. If you do the same commands but omit -buildmode=pie the correct file/line information is shown.
I have a partial fix for this, but a full fix requires applying the dynamic relocations to the pclntab data. The RELATIVE dynamic relocations can be ignored, but there are some non-relative relocations to symbols defined in runtime/cgo.
