Set the ABI in the ELF header to \fInumber\fP.
The default value is \fI3\fP for Linux.
.TP
.B \-b
Write a big-endian ELF file.
.TP
.B \-h
Print a help message and exit.
.TP
.B \-l
Write a little-endian ELF file.
This is the default.
.TP
.BI \-m number
Set the machine type in the ELF header to \fInumber\fP.
The default value is \fI3\fP for Intel 386 (i386).
Other values are \fI4\fP for Motorola 68000 (m68k)
and \fI20\fP for PowerPC.

The output file has ELF section headers if and only if it has symbols.
