 Markos> Peter,

 Markos> After this commit I am seeing this problem

 Markos> Applying libcap-2.22-build-system.patch using patch:
 Markos> patching file libcap/Makefile
 Markos> patching file Make.Rules
 Markos> make: *** No rule to make target `host-attr', needed by `host-libcap-depends'.

 Markos> I am not sure what tirggers it. Any ideas? host-attr shouldn't be
 Markos> needed as I removed that from  LIBCAP_DEPENDENCIES

It's because HOST_LIBCAP_DEPENDENCIES defaults to the value of
LIBCAP_DEPENDENCIES, so you need to explicitly set it to the empty
string.

Didn't you see this problem with your version as well? As far as I can
see it isn't caused by my rename.
