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

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,]
