>Description:
Attempting to build the "sysutils/cdrtools" package using cwrappers under
Mac OS 10.11 (XCode tools 7.0.*, configured to use 64Bit ABI) causes
multiple link errors like these:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

All the object files in the work directory of "cdrtools" are in
"Mach-O 64-bit object x86_64" format. as expected The "i386" in the
directory name is an artefact of the pkgrsc "configure" stage and
(probably) not related to the problem at all.

I'm not sure why the link stage breaks although everything seems to
be consistent. The problem doesn't occur when I build without cwrappers.

>How-To-Repeat:
cd pkgsrc/sysutils/cdrtools
bmake USE_CWRAPPERS=yes
