Subject: build-sys: --prefix defaults to /usr
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=15a9b48cf5a8e33e0f64070ca190c6eda586f8b8;p=util-linux

build-sys: --prefix defaults to /usr

Use prefix=/usr as the default setting.  If prefix is /usr, make
bindir and sbindir default to /bin and /sbin, respectively.
