Subject: Put the ldscript parts into a single file instead of storing it as head
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=69e72f4e91bc3b4aa05108ecd763078497c7d584;p=openbsd

Put the ldscript parts into a single file instead of storing it as head
and tail and cat(1) it together.  It was maybe needed when ports needed
different contents, but now it's just a headache.
