cmd/internal/objfile: read file/line information for ELF PIE binaries For PIE binaries, the .gopclntab section doesn't have the usual name, but .data.rel.ro.gopclntab. Try the relro version as well. If both failed (e.g. for externally linked PIE binaries), try runtime.pclntab symbol. This should make cmd/objdump able to print the file/line information for PIE binaries. I attempted to do this a few years ago, but that wasn't enough, because the pclntab itself contains dynamic relocations which are not applied by the tool. As of Go 1.18 the pclntab is mostly position independent and does not contain dynamic relocations, so this should be possible now. Fixes #17883. Updates #46639.
