[PATCH] Fix gdb.compile/compile.exp shlib regression

Commit 6e774b13c3b8 (Make ftrace tests work with remote targets) made
a few gdb.compile/compile.exp tests disappear:

-PASS: gdb.compile/compile.exp: call shared library function
-PASS: gdb.compile/compile.exp: expect 1
-PASS: gdb.compile/compile.exp: modify shared library variable
-PASS: gdb.compile/compile.exp: expect 15

This is because the test uses ldflags instead of using the shlib
option, so it misses linking with -rpath, resulting in:

(gdb) run
Starting program: .../compile/compile-shlib
.../compile/compile-shlib: error while loading shared libraries: compile-shlib.so: cannot open shared object file: No such file or directory
[Inferior 1 (process 18014) exited with code 0177]

I also noticed we were missing a gdb_load_shlibs call.

gdb/testsuite/ChangeLog:
yyyy-mm-dd Pedro Alves <palves@redhat.com>

* gdb.compile/compile.exp: Use gdb_compile with "shlib=" option
instead of build_executable. Use gdb_load_shlibs.
