/* More recent versions of binutils mark SysV objects as Linux objects
 * if they use certain GNU extensions (which we do).  We could solve
 * this problem directly by declaring and using ELFOSABI_AKAROS,
 * but that requires changes to all of GCC, BFD, GAS and GLIBC.
 * Instead, we take the easy way out: accept all SysV and Linux objects.
 * Most importantly, both Kevin and Andrew concur on this matter. */
