Yann E. MORIN e7930b65c0 package/libcap: needs headers >= 3.0
libcap requires XATTR_NAME_CAPS, which was introduced in Linux 2.6.24.

However, we have some toolchains, liek the CodeSourcery PowerPC 2011.03,
that is missing those defines, even though it uses headers from Linux
2.6.38.

Since there is no perfect way to avoid the situation, just require
headers >= 3.0 to build libcap.

Propagate the new dependency to packages that select libcap.

Fixes a lot of build failures, of which:

help
This library implements the user-space interfaces to the
POSIX 1003.1e capabilities available in Linux kernels. These
capabilities are a partitioning of the all powerful root
privilege into a set of distinct privileges.

Install setcap, getcap, getpcaps and capsh tools.
For these tools to run properly, you should enable, in your
kernel configuration, extended file attributes/security labels
support for the file system type used on target system (e.g.
CONFIG_EXT2_FS_XATTR and CONFIG_EXT2_FS_SECURITY for ext2).
