There doesn't seem to by any test for the load command. I suggest to
add this test, so that we can have a minimum of confidence we don't
break it completely while refactoring the code that implements it.
gdb/testsuite/ChangeLog:
* gdb.base/load-command.c: New file.
* gdb.base/load-command.exp: New file.
* lib/gdb.exp (gdb_is_target_remote_prompt): Rename to...
(gdb_is_target_1): ...this, and generalize for other targets
than just remote.
(gdb_is_target_remote): Use gdb_is_target_1.
(gdb_is_target_native): use gdb_is_target_1.
