You are looking at the wrong place. Your clock.rel seems to be
bsp-specific, so it should be contained in librtemsbsp.a.

You might want to look into your BSP's
c/src/lib/libbsp/<cpu>/<bsp>/wrapup/Makefile.am

and compare it to the Makefile.ams of similar BSPs.

You probably also need to adapt your BSP's bsp_specs.

[Background: Since 4.5, librtems.a has been split into librtemscpu.a and
librtemsbsp.a, so you need to reflect this change to your bsp_specs,]
