package/linux-tools: rtla: Pass TARGET_LD to the make arguments

In Linux v6.8,  the rtla Makefile was rewritten :

  01474dc706ca ("tools/rtla: Use tools/build makefiles to build rtla")

The new Makefile uses default linker values, so the host linker being used to
produce the final rtla binary.

This results in the following error :

ld: [...] trace.o: error adding symbols: file in wrong format

Add LD=$(TARGET_LD) to the RTLA_MAKE_OPTS to fix rtla cross-compilation.
