override LDFLAGS with debhelper 7

[Fathi Boudra <fabo@debian.org>]

Hi,

It seems the best (only?) way to override LDFLAGS with debhelper 7 is
a LDFLAGS export at the top of debian/rules file.

However, there's some packages using another method:
override_dh_auto_configure:
    dh_auto_configure -- LDFLAGS="$(LDFLAGS) -Wl,--as-needed"

NOTE: this method doesn't work !

Should we track this packaging error and fill bug against them ?

Cheers,

Fathi
