disk_label.so shouldn't be packaged on sparc
A SPARC build with 10569 applied gives the following failure:
Entries present in manifests but not proto area:
file NOHASH group=sys mode=0555 owner=root path=usr/lib/mdb/raw/disk_label.so
file NOHASH group=sys mode=0555 owner=root path=usr/lib/mdb/raw/sparcv9/disk_label.so
The disk_label code isn't built on SPARC (which is why it's not in the proto area), but it's little-endian only, and poking around mbr and gpt isn't particularly relevant on SPARC, so we should just make sure this module is omitted from the SPARC package.
Looking at it, the usr/lib/mdb/raw directory isn't needed either.
