global destructors on mips-elf

[Joel Sherrill <joel dot sherrill at OARcorp dot com>]

Hi,

Background: I am trying to construct an RTEMS BSP for the 
jmr3904 MIPs simulator in gdb.  I have a simple hello world
running with one glitch.  The global destructor table must
be incorrectly constructed since the program locks up when
__do_global_dtors.  I based my linker script on the 
ones in libgloss.  Does anyone have a working example for
mips-elf that actually runs the global destructors properly?

I have attached the linker script if anyone can spot anything.
It has to be my fault. :)

Thanks.
