>Description:
Binutils 2.16.1 and patches in -current produces invalid jump table code to plt 
section which results in SIGILL's when running the thumb mode binaries. 
Userspace, including libc, were compiled to -mthumb where possible (and where 
not to ARM with -mthumb-interwork) according to build script available from 
http://mail-index.netbsd.org/port-arm/2008/09/19/msg000387.html .

For better explanation:

>How-To-Repeat:
Build libc and userspace in thumb, try running the binaries on ARM.
>Fix:
* use -mlong-calls as suggested in 
http://mail-index.netbsd.org/port-arm/2008/09/05/msg000362.html

or

* upgrade binutils to 2.18.50, patches available from
