Hello Fabrice,
Sorry for the slow feedback on this one.

So, this happens because when BR2_SHARED_LIBS=y, gnutls installs only a
shared library, while libcap installs both a static library and a
shared library.
But really, the crux of the problem is that LXC shouldn't try to build
a statically linked program when BR2_SHARED_LIBS=y. It doesn't make
sense, because we don't guarantee to provide static libraries when
BR2_SHARED_LIBS=y: some packages do build static libraries
unconditionally, but for examples the autotools packages that obey to
--disable-static will not build/install static libraries when
BR2_SHARED_LIBS=y.
And in fact, I'm wondering how your patch resolves that really. I guess
it disables GnuTLS support in such a situation, but that isn't really
the right fix IMO. I would rather disable the build of the static
version of the LXC program.
Do you think you could have a look into this ?
