If I run single test solib-list.exp, it is OK. If I run two, as below,
there are fails,
$ make check RUNTESTFLAGS="server-run.exp solib-list.exp"
FAIL: gdb.server/solib-list.exp: non-stop 0: continue (the program exited)
FAIL: gdb.server/solib-list.exp: non-stop 0: p libvar
FAIL: gdb.server/solib-list.exp: non-stop 1: continue (the program exited)
FAIL: gdb.server/solib-list.exp: non-stop 1: p libvar
in gdb.log,
/scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/server-run/server-run /lib64/ld-linux-x86-64.so.2 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/solib-list/solib-list
server-run is spawned, which is wrong. If I only run solib-list.exp, ld-linux
is spawned, which is right.

in test, we spawn gdbserver this way,
# Note we pass ${interp_system}, the program gdbserver spawns, as
# argument here, instead of using gdb_load, because we don't want
# to download the interpreter to the target (it's already there)
# or to the test output directory.
set res [gdbserver_spawn "${interp_system} ${remote_binfile}"]
in gdbserver_spawn -> gdbserver_download_current_prog, if
last_loaded_file is set (when you run multiple tests), it is
returned.
This patch is to unset last_loaded_file in solib-list.exp.
