[Click] Recent commit broke click build on openwrt

[Eddie Kohler]

Roberto,

The question is why your compiler declares clock_gettime *and* appears to 
define clock_gettime, but linking with clock_gettime fails?  My change was 
designed to search for a clock_gettime definition.

A complete config.log may help.
