I have similar issues.
I tried to compile Suitesparse to a newer version and Sundails, but that
failed, so I restored the previous versions through Mageia's package
manager.
But since then Octave cannot find the colamd, ccolamd and other
suitsparse-related libraries, in spite of explicitly supplying the relevant
configure option.
That bites a bit as I can't make dist targets anymore for cross-building in
mxe-octave.

But I didn't pursue further as I have another build box that is still
working properly.
(Yes I compared the various libs and files on those boxes, but found no
differences so I gave up)
