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:

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).
