Hexagon: implement machine flag check

This fixes the "invalid machine flag" error from eu-elflint when passing
hexagon binaries.

        * backends/hexagon_init.c (hexagon_init): Hook
        machine_flag_check
        * backends/hexagon_symbol.c (hexagon_machine_flag_check):
	new function
        * libelf/elf-knowledge.h: add EF_HEXAGON_TINY constant
