it is enough to use gdbserver:
	http://sourceware.org/gdb/wiki/TestingGDB#Testing_gdbserver_in_a_native_configuration

I have put there a debug dump and for example for gdb.base/return.exp it
really prints several SVR4:PASS and no SVR4:FAIL.

There are some corner cases where solib-svr4.c logic may be used but those are
only rare and discussed in some past gdb-patches mails.

Could you be more specific how do you run the test and how have you found
gdb/gdbserver/linux-low.c is not used?


Thanks,
Jan
