libvalhalla: Add recipe for libvalhalla 1.0.1.
1. `--enable-pic` is needed for non-x86 architectures.
2. Put test programs in separate package `${PN}-bin`. Manual pages are in `${PN}-doc` though.
3. Build tested with GCC 4.4.3 and Binutils 2.20.1 for `MACHINE = "beagleboard"`.
4. Depend on `libnfo` since it is recommended on upstream’s Web site.
`do_configure()` is based on the recipe of `ushare`.
