Well, ignored then.  The build continues but builds an strace without
mpers support.

If the target defaults to running mpers, yeah, I think a test for [][]
support in configure would be appropriate (or making the test
fatal), perhaps with an --disable-mpers to work around it.

Building an strace that doesn't do what you expect is worse than not
building an strace until you change your expectations ;-)

Or if mpers is not built, at least strace should refuse to trace
binaries that would have required the other personalities.  At the
moment, it traces them but produces incorrect output.
