[Buildroot] [PATCH 2/3] package/rpm: use external xz library

[Yann E. MORIN <yann.morin.1998@free.fr>]

Romain, All,

On 2015-01-18 12:34 +0100, Romain Naour spake thusly:

Weird, this build error is about being unable to link with libintl.so
(indeed while building the xz backend, but still about libintl).

Igues I could use that autobuild failure to test your patch 1/3,
though...

Otherwise, I have some comments, see below...

I know you are fixing existing code, but we usually do not have such
sub-options, and we instead rely entirely on the dependant package in
the .mk, without adding such sub-options...
