FUNCTION
bfd_alt_mach_code
SYNOPSIS
boolean bfd_alt_mach_code(bfd *abfd, int index);
DESCRIPTION
When more than one machine code number is available for the
same machine type, this function can be used to switch between
the preferred one (index == 0) and any others. Currently,
only ELF supports this feature, with up to two alternate
machine codes.
