 658 # Getting this done right is going to be a bitch.  Each configuration specified
 659 # with --enable-targets=... should be checked for environment, format, cpu, and
 660 # bfd_gas setting.
 661 #
 662 # For each configuration, the necessary object file support code must be linked
 663 # in.  This might be only one, it might be up to four.  The necessary emulation
 664 # code needs to be provided, too.
 665 #
 666 # And then there's "--enable-targets=all"....
 667 #
 668 # For now, just always do it for MIPS ELF or ECOFF configurations.  Sigh.
