[klibc] ia64: Fix out-of-tree build

Origin: https://git.kernel.org/pub/scm/libs/klibc/klibc.git/commit/?id=2114e20cf16bbfb45a94aaf978d62d08d8968414

The linker script is currently not found in an out-of-tree build.
The filename needs to start with $(srctree) to make this work.

it in addition to all the options we need.
