Give the syscall a pseudo name based on its ABI. For example
a FreeBSD 64 #550 would become FreeBSD_ELF64_550.

Note that it doesn't show the *arguments* properly. I'm not quite sure why. If I assign narg = 10 it just shows:
FreeBSD_ELF64_550(0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0) ERR#78 'Function not implemented'
