Smell like a libtool script bug (convert is executed thru a libtool
script during build).

Do you have inkscape installed during build ? If so convert will use inkscape.

I have no idea why the wall time are so different. We have already
disable test suite for mips with no FPU, and I have no trust of
imagemagick result if I could not run at least one conversion. So even
if it take 5h it will catch RC bug.

That why I have added the print in order to keep going. Without
testsuite, it is hard to know if mips is working.
