Workaround for a system call bug in older "libattr" libraries of ARM targets
- Older "libattr" libraries for ARM use an incorrect format for some
system calls; Maemo's patched qemu now has workaround for that. Now sb2
detects if the selected qemu knows about this "libattr hack" and
enables it if possible.
