OK for Microblaze.
There appear to be other places where buildargv() is not followed by
freeargv(). See sim/common/run.c. There may be others.
For me, I intended to skip buildargv() in "sim/common/run.c", because it
may contents read only memory. It is in main(), also main() often uses
exit(), so I skip it, it doesn't matter.
gdb also uses buildargv(), but it just wraps buildargv() and freeargv(),
so at least it is another patch (either, at least now, I do not find any
issues about it in gdb).
Except the above 2, for me, there are no any other places to use
buildargv().
Does the patch comments need to mention about the contents above?
