0.8.8.25:
	More SB-POSIX test fixes
	... allow building as root again, since it seems that's a
		desired feature
	... test for not having EUID of 0 in EACCES posix tests instead

	(this will probably annoy antifuchs, but I forgot to commit
	version.lisp-expr for the last fix.  Since this is logically a
	simple continuation, I haven't bothered to increment it again)
