/usr/lib/crtstart.o contains a .note.netbsd.ident section.
NetBSD's bundled compiler links crtstart, crtend, crt0, ... into an executable.
The kernel (current) refuses to run NetBSD executables unless: they contain the above .note section or the kernel is configured with ``options EXEC_ELF_CATCHALL''.
Unfortunatly, unbundled complers (eg GCC>3.0) typically don't use system supplied files such as crtbegin.o - instead they supply their own. Consequently, an unbundled compiler won't include the crtbegin.o .note section and, in turn, won't be able to generate binaries that can be run on NetBSD-current.
Further, the error message printed when you run such a binary is totally unhelpful.
Build an executable that does not contain a .note section.
Revert rev 1.57 of kern/exec_conf.c.
