illumos gate

When running wsdiff against two workspaces with no changes to the ACPI tools, I noticed they nonetheless appear to have some differences:

usr/sbin/iasl

It would appear that these timestamps are included in support of an unhelpful command-line option:

root@jenkins-oi0:~# /usr/sbin/acpidump --help
Illegal option: --
Usage: acpidump [options]
Options:
...
  -v                  Display version information
  -vd                 Display build date and time
...

The output of -vd is, e.g.,

root@jenkins-oi0:~# /usr/sbin/acpidump -vd

We should figure out a way to patch this out of our copy of the tools. Note that we don't necessarily just want to patch the source in the tree directly. See notes in #9824 for how we're managing ACPI updates.
