ld/testsuite/lto: replace manual links by ld_link helper

Some tests are calling run_host_cmd in order to retrieve the
errors/warnings messages generated.
ld_link is also making them available through exec_output global
variable but as the advantages of taking the board configuration into
account unlike run_host_cmd.
