arch/arm-all: Fix NewStackSwap under gcc 4.6.x
Under certain optimizations, the gcc constraints for the assembly
section of Exec/NewStackSwap would use '%lr' as the register
replacement for 'entry', causing NewStackSwap to return early
instead of calling the desired entry point.
'%lr' has been added to the asm () clobber list, and the code
is correctly generated now.
