you don't need to modify the configure script. What you have do is to 
call configure with the right environment variables for your toolchain 
(CXX and possibly also others) and to set the target architecture with 
the --host parameter.

For example I use the following command line to compile gnash for our 
CRIS-based embedded board:

CXX=g++-cris -mlinux -mno-mul-bug-workaround \
LD=ld-cris \
RANLIB=ranlib-cris \
AR=ar-cris \
./configure --host=cris-axis-linux-gnu \
  --enable-renderer=agg \
  --enable-gui=fb \
  --with-agg-incl=/home/hannes/agg-2.4-cris/include \
  --with-agg-lib=/home/hannes/agg-2.4-cris/src \
  --disable-sound \
  <...more gnash options and dependency paths...>

I've successfully cross-compiled gnash some time ago, but in the 
meantime there were a lot of changes, so I can't tell if it still works 
without (little) code modifications.

Besides, don't forget to compile the dependencies for your architecture 
too (libjpeg, libz and especially the boost library is a pain to compile).
