Hi,

This error seems to occur on armel only. Affected is the package aspectc++, which FTBFS because of this bug.
Please see the buildlog at https://buildd.debian.org/status/fetch.php?pkg=aspectc%2B%2B&arch=armel&ver=1%3A2.2%2Bgit20170823-1&stamp=1503642904&raw=0

The relevant part reads like this:

[...]
/usr/bin/make -s -C AspectC++ cleanall FRONTEND=Clang LLVMCONF=/usr/bin/llvm-config-4.0
