Subject: fix for ld.so @ bitcode build
X-Git-Tag: v3.3.0~417
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/doc/processing.js?a=commitdiff_plain;h=4193f2292e5a003332da93c3292274c742a29716;p=minix.git

fix for ld.so @ bitcode build

ld.so linked with gold didn't work - gold was not generating
the _DYNAMIC ptr in the first GOT entry, leaving it zero, causing
mayhem for ld.so.

  . patch for gold: always generate _DYNAMIC ptr. submitted upstream,
    more info here: https://sourceware.org/bugzilla/show_bug.cgi?id=16900
  . revert "REMOVE ME: Static tests for now" - we can link tests dynamically
    This reverts commit 3e0a3993deb831eb5abcd1c1a2cb1246b43f8d1d.
