microblaze: fix setjmp/longjmp
Sync mostly with GNU libc implementation of setjmp/longjmp. Just generate PIC compatible code, so no difference for static builds are made. Add sysdep.h with some handy assembly macros used inside setjmp.S/__longjmp.S. This unbreaks dynamic linker support, first test suite run only shows 10 errors, which doesn't look so bad.
