Your milage may vary depending on what hardware you have.   Personally
I find it 3-4 times quicker to build (considering it takes about 24+
hours to built gdc on a RasPi device).

What's been done is a chroot system has been set-up with ARM binaries,
instead of i386 or x86_64.  qemu-debootstrap installs an executable
qemu-arm-static inside this chroot, so when you try to run any ARM
binaries, qemu kicks in and acts as an emulator.

To compile, simply following the same instructions as per the gdc
wiki.   apt-get install all build deps, retrieve source, ./configure
and make.  :-)
