Bug Description
clang++ -flto does not seem to configure everything properly:
$ clang++ -stdlib=libc++ try.cpp -O3 -flto -Wall -Wextra
/tmp/try-1083b9.o: file not recognized: Dateiformat nicht erkannt
clang: error: linker command failed with exit code 1 (use -v to see invocation)
$ clang++ -stdlib=libc++ try.cpp -O3 -flto -Wall -Wextra -B/usr/lib/gold-ld
however, works properly.
See the attached files for output from the same commands with "-v" added on the respective command lines.

The only difference that -B makes is running /usr/lib/gold-ld/ld instead of /usr/bin/ld
