SPARC/Solaris does a bit better in file size by fitting 46 bytes of code
into a 316 byte file, using the same trick in replacing syscall with its
trap representation.

.section ".text"
        .global start
start:
        mov 4,%o0
        sethi %hi(message),%o2
        mov 1,%o1
        or %o2,%lo(message),%o2
        mov 14,%o3
        ta 8
        mov 1,%o0
        ta 8
message:
        .asciz "Hello World!\n"
