Winebuild b0rken on Mac OS X?

[Charles Davis]

While building Wine (latest git) on Mac OS X, I noticed this:

/usr/bin/nm: object: amstream_test.MDsdpi.o malformed object (LC_SEGMENT
command 0 filesize field greater than vmsize field)

Something's gone horribly wrong. Winebuild shouldn't be generating
b0rken Mach-O files. What gives?
