[LLVMdev] Building on x86-64

[David Greene]

I made my first attempt to build on an x86_64-unknown-linux-gnu system.
Is this supposed to work?  I get libtools errors (below).  The problem seems
to be that it finds a 32-bit libltdl rather than the 64-bit libltdl.

  /home/dag> ls /usr/lib/libltdl.so.3.1.0
  /usr/lib/libltdl.so.3.1.0
  /home/dag> ls /usr/lib64/libltdl.so.3.1.0
  /usr/lib64/libltdl.so.3.1.0

Is this a known problem?  I'm not very familiar with how libtools works so I'm
a bit hesitant to hack up ltmain.sh.
