Comment (by billy@…):

 I'm going to need some help here. While I can build gcc using the approach
 recommended at http://www.codeconfidence.com/technote-0003.shtml I first
 have to install a newlib version using the attached Portfile.newlib, then
 manually copy the ecos headers to /opt/local/arm-eabi/sys-include, then
 build using the attached Portfile.no-newlib. So here is exactly what I do:

 cd ~/ports/cross/arm-eabi-gcc
 cp Portfile.newlib Portfile
 cd ../..
 portindex
 sudo port -d install arm-eabi-gcc (and wait several hours)
 cd ~/ports/cross/arm-eabi-gcc
 cp Portfile.no-newlib Portfile
 cd ../..
 portindex
 sudo port -d install arm-eabi-gcc (and wait several hours)

 It builds clean but doesn't activate the last build because it thinks it
 is already activated. I've read the MacPorts Guide multiple times and
 can't see a path forward even though I can probably get to something to
 work for me personally. I suspect if I knew enough about building gcc I
 could put the includes somewhere and configure it to look for them there.
 Note that if I use Portfile.no-newlib on a completely clean system with no
 arm-eabi-gcc installed it fails.
