Unexpected gcc linking behavior on -CURRENT

[Matt]

Hello all.

I've been working on getting VirtualBox to build on -CURRENT and have
hit what I think might be a compiler snag based on the error and some
of the mails I've seen to the freebsd-java mailing list over the last
months.

Any insights into how to isolate and hopefully correct this error
would be greatly appreciated.  The code builds cleanly on a
6.2-RELEASE box using gcc 3.4.6.  The error on -CURRENT (from 9/13)
using gcc 4.2.1 is as follows:

kBuild: Linking
