It must find /opt/djgpp/i586-pc-msdosdjgpp/bin/as (It should be installed
when installing binutils). You can make it as symlink to 
/opt/djgpp/bin/i586-pc-msdosdjgpp-as. The same about ld in the same
directories.

No. They are not required to get working cross-gcc for
i[3456]86-pc-msdosdjgpp target.

Main reason why I specified them when configuring GCC were to give
configure a possibility to analyse binutils functionality (otherwise
it defaults to most basic functionality only).

And I hope for the same target (for example cross-gcc for
i586-pc-msdosdjgpp and cross-binutils for i686-pc-msdosdjgpp will
not work together)

Make sure You really have 
	/opt/djgpp/bin/i586-pc-msdosdjgpp-as
	
You may have also 
	/opt/djgpp/i586-ps-msdosdjgpp/bin/as
(It is installed by 'make install' when installing binutils. I replacing
it by symlink to the first file)
