can't read "target_info(target,ldflags)": no such element in array

[Tom de Vries]

The current failure in target.test is:
...
can't read "target_info(target,ldflags)": no such element in array
    while executing
"if { $target_info(target,ldflags) == "-Tidp.ld" } {
    incr matches
}"
    (file "../src/testsuite/runtest.all/target.test" line 76)
...

The test fails here:
...
push_config target idp
set matches 0
if { $target_info(target,name) == "idp" } {
    incr matches
}
if { $target_info(target,ldflags) == "-Tidp.ld" } {
    incr matches
}
...

It seems that the test assumes that "push_config target idp" sets 
$target_info(target,ldflags).

But looking at the implementation, it seems we just set 
target_info(target,name):
...
proc push_config { type name } {
    global target_info

    verbose "pushing config for $type, name is $name"
    if {[info exists target_info($type,name)]} {
        if { $target_info($type,name) == $name } {
            error "pushing config for $type, '$name' twice"
        }
    }
    set target_info($type,name) $name
}
...

I'm not sure if the test is incorrect, or the proc.

Thanks,
