Alexander Graf 3fcb714758 sandbox: Fix setjmp/longjmp 
In sandbox, longjmp returns to itself in an endless loop because
os_longjmp() calls into longjmp() which is provided by U-Boot which
again calls os_longjmp().

Setjmp on the other hand must not return because otherwise the
return freees up stack elements that we need during longjmp().

The only straight forward fix that doesn't involve nasty hacks I
could find is to directly link against the system setjmp/longjmp
implementations. That means we just provide the compiler with
hints that the symbol will be available and actually fill them
out with versions from libc.

This approach should be reasonably platform agnostic
