[commit] gdb.base/Makefile.in (EXECUTABLES): Add completion.

[Doug Evans <dje at google dot com>]

Hi.

I was seeing the following failures.

FAIL: gdb.base/completion.exp: complete target core ./gdb.base/completion
FAIL: gdb.base/completion.exp: complete target tfile ./gdb.base/completion
FAIL: gdb.base/completion.exp: complete target exec ./gdb.base/completion

A bit of head scratching and digging later, I found them due to
this bit of code in completion.exp:

foreach dir1 [ list "./gdb.base" "./outputs/gdb.base/completion" ] {
    if [remote_file host exists ${dir1}/completion] {
	foreach target_name ${targets} {
	    gdb_test "complete target ${target_name} ${dir1}/completion" \
		"target ${target_name} ${dir1}/completion.*${dir1}/completion0\\.o.*${dir1}/completion1\\.o.*"
	}
	break
    }
}

If you test completion.exp first in serial mode,
do a make clean in the testsuite directory,
and then run the test in parallel mode, that will trigger these
failures.

Either of these changes will fix the problem.
Applying both for completeness sake (heh).

Regression tested on amd64-linux and committed.

	* gdb.base/completion.exp: Check that all expected files exist
	before doing file completion.
