arm-rtems/elf -mthumb bad code generated

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

CVS gcc, binutils, newlib

I think this is the bad assembly based on the error messages

        @ Inlined umul_ppmm
        mov     r1, r2, lsr #16
        mov     ip, r3, lsr #16          

This is the command line to get the preprocessed output.

This is the command line to reproduce the error:
