 Thanks for grate work :-)
 We should integrate these changes into Debian distribution tree.

 I have some a question.

 Debian have only binary-sh tree currently. It is contains binary for
SH3 little endien environment.

 But ABI level incompatibility does exist between SH3 binary and SH4
binary, so binary for SH3 can not run on SH4 binary environmet.
Of cause little endien and big endian incompatibility does exists.

 So, 4 separated binary arcitecture tree?

  binary-sh3, binary-sh4, binary-sh3eb and binary-sh4eb

 Is it true?
