I noticed such problems when I was testing compressed debug
sections. I did:

1. Build a special assembler with compressed debug section enabled
by default.
2. Use the new assembler to compile and run "make check" on
Linux/x86-64 with gcc, glibc and gdb.
3. Run gdb on newly built gcc and glibc.

If we want to rename section names, I think we should enable the
compressed debug in assembler by default.  Otherwise, we may
not know if there is a problem.

BTW, gdb 7.0 and above support compressed debug sections.
