/* NOTE: This is almost identical to what is in crt1.s. crt1.s is used when
         compiling with the real cross compiler, while start.s is used when
         using the older hacky way of building Sortix. Please try to keep these
         files alike by doing changes both places until we only build Sortix
         with real cross compilers. */
