Any ideas?
Sorry about this. I missed a critical flag (--eh-frame-hdr) that gcc specifies implicitly when converting the Makefile to invoke ld directly. This went unnoticed because the linking of vmlinux (which also uses ld directly) does not need this information, so it does not specify the flag. Sending a verified fix now.
