[Patches] [MIPS] Use ia64 backtrace.c.

[Tom de Vries <Tom_deVries@xxxxxxxxxx>]

Joseph,

this is the eglibc version of the approved
http://sourceware.org/ml/libc-ports/2011-12/msg00052.html, which additionally
enables -funwind-tables for tst-backtrace{2,3,4,5,6}, which allows them to pass.

Thanks,
- Tom
