Prefer arch-specific linker config when available

New linker configuration from /linkerconfig is not suitbale for emulated
architectures. But as of now, native_bridge linkers pick it up as well
and thus fail to find the libraries for emulated architectures.

This is a (temporary) fix so native_bridge linker still picks up
configuration from old location.

Bug: 138920271
Test: native_bridge linker works
