So, the problems with building the arm32 port fall into 3 categories:

1) Some programs (sa, dhcpd) didn't build due to compiler bugs.  I've
   fixed the compiler bugs; just rebuild and install it, and it's no
   longer an issue.

2) gas.new doesn't work correctly for PIC.  Don't use it.

3) ld/ld.so have been hacked to do something absolutely horrible for
   PIC code on the ARM.  This hack is unnecessary, and should be
   removed.  However, doing so breaks compatibility with old shared
   libraries.

If you don't touch as, ld or ld.so, the rest actually does work.
