scripts: add option to start an interactive debug shell

Add an option that, when a command fails:
- starts an interactive shell with the failed command's environment
- attempts re-execution of the failed command, continues, or aborts
at user's whim.

Before starting the debug-shell, the backtrace is printed.
When exiting for an abort, the standard error message is printed.

Based on an idea and a patch from: Johannes Stezenbach <js@sig21.net>
http://sourceware.org/ml/crossgcc/2012-09/msg00144.html

ARMV5 can use STRD and LDRD access instructions but these accesses need to be 
yann@1248
     5
8 byte aligned. The dynamic linker's malloc needs to match this so structures
yann@1248
     6
become 8 byte aligned to void unaligned accesses.
