Subject: Add Configure option -Dmksymlinks which will create a symlink
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=dafca956013a09f7b5201b464199f47cf100f00f;p=p5sagit%2Fp5-mst-13.2.git

Add Configure option -Dmksymlinks which will create a symlink
forest if the current/build differs from the source directory.
TODO: mkdir -p is not portable.
