[Buildroot] [PATCH 1/1] rpm: disable static build support

[James Knight]

The RPM package requires dynamic linking support (dlfcn.h) for its
capabilities related to plugins (and possibly more). The following
commit adds a dependency to !BR2_STATIC_LIBS.

Indirectly fixes (see [1]):

Although I agree that a depednency on !static is correct because of the
use of dlfcn.h et al., the autobuild failures you report are, as you
said, unrelated: rpm fails to build because it does not link with -lz.

So I don't think they should be in the commit log. You may put them in
a post-commit-log (after the --- line), though.

And I tend to agree with there reasoning. Besides, this is not enough
because popt then fails to link because it misses symbols from libintl.
And so on...

Otherwise, I'm OK with that.

Ok; I'll cleanup the commit message and resend.

Thanks for the comments.
