These builds all fail with something like:
  CCLD   libclamav.la
ld: warning: ignoring file ../libclamav/libclamav.map, file was built for unsupported file format ( 0x43 0x4c 0x41 0x4d 0x41 0x56 0x5f 0x50 0x55 0x42 0x4c 0x49 0x43 0x20 0x7b 0x a ) which is not the architecture being linked (x86_64): ../libclamav/libclamav.map
Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I only really have access to mavericks systems now, but I was able to reproduce this issue with the Xcode 5 devtools (everything builds fine with the Xcode 5.1 devtools). I tried blacklisting clang < 503.0.40, but that didn't help (it caused an install of llvm-gcc42 cctools cctools-headers llvm-3.3 llvm_select gcc_select ld64, and presumably used llvm-gcc42 to try to build). Anyone have any thoughts on what may be going on?
