I finally got buildroot deliver the file system so I could test my
page size fix. Now at least busybox and dash work, bash still hangs.
Also default uClibc config enables CONFIG_FEATURE_TASKSET_FANCY, which
wants unimplemented functions. GDB needs threading support, but none
of the build options were satisfactory. I forgot why I didn't get
strace building.
I'll test Sparc64 next.
