Download source only on remote host

There is no need to download source if we aren't on remote host.
Otherwise, each ld test run on local host leaves behind a couple
test files.

	* config/default.exp (NOPIE_CFLAGS): Download source only on
	remote host.
	(NOPIE_LDFLAGS): Likewise.
	* testsuite/lib/ld-lib.exp (check_lto_available): Likewise.
	(check_lto_fat_available): Likewise.
	(check_lto_shared_available): Likewise.
	(check_ifunc_available): Likewise.
	(check_ifunc_attribute_available): Likewise.
