[Debian-med-packaging] Extra patch for ARB : --enable-new-dtags

[Tim Booth]

Hi Elmar and Andreas,

I notice that a lot of work has gone into packaging the new ARB 6 so I
had a go at backporting the package for Bio-Linux (Ubuntu 14.04).  I
found that a basic "debuild -b" failed because of the old ARB 5.5
package installed on the system.  OK, I can remove the old ARB package
or else pbuild it no problem, but I did a bit of digging and came up
with the attached patch.

I'm sending it via the list rather than bunging it into SVN because I
want you to look at it and tell me if you've come across the
--enable-new-dtags thing before?  It looks like this should be the
default behaviour for all builds but some distros have adopted it and
others (Debian) did not.

Aside from fixing my build, this also restores what (to me) would be the
expected behaviour for $LD_LIBRARY_PATH in the binary package, so I
would advocate applying this to the package for that reason.  But maybe
it has a downside I missed?

Any thoughts?

TIM

Apparently back in 1995 the ELF standard was tweaked to handle some
crufty behaviour of RPATH - see http://blog.tremily.us/posts/rpath/
but Debian never adopted it.  But for this package we do want it, so
edd the extra linker flag.
