Are there any Linux programs that can disassemble an OSX universal x86/x86_64 fat Mach-O binary like objdump? GNU binutils' objdump supports ELF and Windows PE files but not Mach-O.

AFAIK, the native Darwin binary tools are part of the cctools package. They don't have the same command line syntax or output as the GNU binutils. Later binutils (i.e., 2.22) supports the Mach-O format however. You can get these prebuilt, with the 'g' prefix to the tool names, as mentioned here. Alternatively, you can compile binutils, with something like:

> ./configure --prefix=$CROSSTOOLDIR --target=x86_64-apple-darwin \
--enable-64-bit-bfd --disable-nls --disable-werror

Installation will yield a bin/ directory where the utilities are prefixed with x86_64-apple-darwin. It should handle i386 Mach-O format (and FAT binaries) fine.
