 	F_LSYMS		local symbols stripped from file
        F_INTERWORK     file supports switching between ARM and Thumb instruction sets

 	F_AR32WR	file has byte ordering of an AR32WR machine (e.g. vax)
 	F_APCS_26	file uses 26 bit ARM Procedure Calling Standard
 	F_APCS_SET	the F_APCS_26, F_APCS_FLOAT and F_PIC bits have been initialised
 	F_SOFT_FLOAT	code does not use floating point instructions.  */
