Subject: fix "configure --prefix=" and improve path/arg handling in configure
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=3d9e3a309f794faf0df53c00b15d406f14931938;hp=3d9e3a309f794faf0df53c00b15d406f14931938

fix "configure --prefix=" and improve path/arg handling in configure

previously, empty string was treated as "use default". this is
apparently not compatible with standard configure semantics where an
empty prefix puts everything under /. the new logic should be a lot
cleaner and not suffer from such issues.
