ECL has been compiled directly on the ARM in the past, so I would say
this is not intrinsic to the architecture. The cross-compilation
process, on the other hand, may have been left behind by current
improvements in the code.

One thing that seems to be a must in many ARM environments is to
disable floating point exceptions completely. There is a flag to do
so.

Another thing that you mention in the email is that you left the
default values for the cross-compilation settings and this is not
really a good guess. Those values are telling the ECL build details
about the architecture of your system: direction of stack growth, size
of words and pointers, etc. These things are normally guessed by
running a program during configuration, but since you are
cross-compiling this is not an option. However, getting them right is
critical and putting the wrong values there will produce an useless
executable.
