I had supposed (incorrectly, it seems) that, like GCC, GDB only supported
either the O32 (in the IRIX 5 configuration) or N32/N64 (in the IRIX 6
configuration) ABIs.

While a mips-sgi-irix6.2 configuration is able to debug the O32-with-stabs
hello-gcc that fails in the mips-sgi-irix5.3 configuration, the
O32-with-mdebug binary still triggers the same internal error reported with
my patch.
