From 3628edc05e5b439aad08191ab220360f9d9f54bd Mon Sep 17 00:00:00 2001

Subject: Based on discussions with Stefan Allius, change it so that we always
 build a crt0.o and a crt1.o.  crt1.o will support ctors and dtors if such
 support is enabled.  One more gratuitous toolchain support issue is thereby
 removed...  -Erik
