Interesting, and this does not reproduce for me.  

I've tried "run twice back to back" like you did above, "run once, then
'find -type f -print | xargs touch' the target, and then run again", and also
"run once, then 'find -type f -print | xargs chmod -w' the target, and then run again".

None of these fail.

One way I can think of to break it deliberately would be:

	make prefix=/var/tmp/gomikuzu quick-install-man
        find /var/tmp/gomikuzu -type d | xargs chmod -w
	make prefix=/var/tmp/gomikuzu quick-install-man

But then the failure is different from what you showed above:

    error: unable to unlink old '/var/tmp/gomikuzu/share/...' (Permission denied)

Puzzled.
