[Buildroot] [git commit] libnl: do not allow to build tools on static lib configs

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=337a59d9e47772c89ecd1e4523e300e5e3c642ce
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Building the libnl tools requires the <dlfcn.h> header, which is not
compatible with static only builds. Therefore, this commit makes the
libnl tools option depend on !BR2_PREFER_STATIC_LIB.

Fixes:
