[PATCH] Share a prevailing name for remove debug info symbols w/ LTO.

[Martin Liška]

Hi.

The patch is about better symbol table manipulation
for debug info objects. The patch fixes reported issue
on hppa64-hp-hpux11.11.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
