 * getabi() is used to determine what the abi is.  
 * First it checks the argv list, 
 * then the environment variable SGI_ABI, 
 * then the kernel (64-bit kernel defaults to 64-bit abi).
 * The generic_size boolean says whether to report the generic
 * size of the abi (abi32 or abi64) or to report the specific abi.
 * The modify_abi_arg says to either ignore the argv list,
 * or search the argv list and either preserve the args "as is",
 * or remove the arg that specifies the abi 
 * or add the default value to the argv.
 * Noabi is returned if an error occurs.
