LIB_SPEC 101:

%{foo:arg} => if the command line contains "-foo" then add "arg" to the
ld command line.

%{foo:%{!bar:arg}} => if the command line contains "-foo" but not "-bar"
then add "arg" to the ld command line.

%{foo:%{!bar:arg}{bar:arg1}} => if the command line contains "-foo" but
not "-bar" then add "arg" to the ld command line or if the command line
contains both "-foo" and "-bar", then add "arg1" to the command line.

Something like that. 8-)

If you grab the LIB_SPEC from current, it will need the kthread references
stripped. "An exercise for the reader". 8-)
