[Libreoffice] ld dynamic linker hash style

Hi all,

During the last few days, my builds have been broken with this error message:
  makedepend: Shared object has no run-time symbol table

I have tracked the start of my troubles to this commit:

        83b781819557f269fda65ce551ec9a008fade511
        
http://cgit.freedesktop.org/libreoffice/bootstrap/commit/?id=83b781819557f269fda65ce551ec9a008fade511

It adds the "--hash-style=gnu" string on ld invocations.
--hash-style=gnu sets the type of linker's hash tables to a new ".gnu.hash"
format.

The problem is, this flag also prevents ld to write classic ELF ".hash"
sections, preventing some systems to be able to run the generated binaries.

Googling a bit, I found references to this issue on all types of systems
See here for a Suse one:

The new .gnu.hash sections are not recognized by old binutils versions such as
2.17 and may or may not be used on more recent ones.
One of my machines is using binutils-2.21 and cannot run binaries linked with
the --hash-style=gnu option. I need to investigate.

Howewer, the fix is quite simple: replace --hash-style=gnu by --hash-style=both
The --hash-style=both option generates both old and new-style sections,
keeping all binutils happy.

The attached patch does just that.
