When I implement setjmp like this:

void
setjmp (jmp_buf env)

then it doesn't work.

Then I implement setjmp like this:

void
setjmp (__jmp_buf * env)

then it does work.

I suspect that env[0].sp = ... is not working as intended for actual arrays (as 
opposed to pointers).  (Might also be broken on i686 but I don't remember)

When debugging I saw that it didn't actually store the data into the jmp_buf 
structure on setjmp but rather stored it on the stack (but the jmp_buf 
structure is a global variable in this test case).

Pushed as commit 436f1c7ae23c4bf5283081a4f5e88f67dc10356b to branch wip-arm.
