Bug#976462: debian bug 976462

[Mark Wielaard <mark@klomp.org>]

For reference, this is the dwz bug for [dwz] Support compressed debug
sections: https://sourceware.org/bugzilla/show_bug.cgi?id=24725

It has low priority because it has a simple workaround:
you could use eu-elfcompress before/after the dwz run

$ eu-elfcompress --type=none ./a.out 
$ dwz ./a.out 
$ eu-elfcompress --type=zlib ./a.out

Also adding elf section (de)compression to dwz would increase memory
use even more for application. And dwz already has to be careful about
memory usage.

Even though adding it is fairly simple since dwz uses elfutils libelf
so it is simply adding appropriate calls to elf_compress (section...)
