It would be nice to have a test for QImode != 8bit, but the sad fact
is that nobody is maintaining the port. Not even the listed
maintainer. With GCC developing rapidly, any port is subject to bit
rot. I hate to say this, but if you want something, whether a healthy
c4x port, or decoupling of modes and bits, you either have to do it
yourself or hire somebody to do it. Keeping a broken c4x port will
not assure that we decouple modes and bits.
On the actual problem of the port not building any more, I believe
Richard Sandiford had a patch that he used to test his option
conversion patch. You might want to search the mailing lists or
contact him for the patch as the first step of reparing the port.
