Package: libc6 Version: 2.3.2.ds1-10 ld.so: Incorrectly built binary which accesses errno or h_errno directly. ld.so: See /usr/share/doc/libc6/FAQ.gz.
The explanation is actually in /usr/share/doc/libc6/README.Debian.gz, and it would be nice to actually print the name of the offending executable, because it often arises deep in a script somewhere that is running many executables. (at least the argv[0], if not readlink("/proc/self/exe")) Other than that, thanks for the workaround!
