It seems CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe" makes gcc use
-fPIC by default (this is from an ncurses attempt)...

gcc -I../test -I. -DHAVE_CONFIG_H -I. -I../include -march=x86-64 -mtune=generic -O2 -pipe -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64  -DNDEBUG -march=x86-64 -mtune=generic -O2 -pipe  --param max-inline-insns-single=1200  -fPIC -c ../test/background.c -o ../obj_s/background.o

To bootstrap, sure, but I'm hoping the Beagleboard, with external USB
HDD, will be powerful enough to build packages natively.

One way to find out :)

"tender loving care". I've had the beagelboard for a couple of weeks
but I haven't even plugged it in yet. http://beagleboard.org/hardware

I should look into it. chroot is simple and native speed.
