Title:
clang++ -flto fails to work unless -B
More importantly, -fuse-ld=gold per apt-get changelog binutils, here,
does NOT work:
binutils (2.23.52.20130722-1) unstable; urgency=low
* New upstream snapshot.
- Fix PR ld/15762, glibc being built without warning sections.
* Set the libdir for arm64 to lib, not lib64.
* Stop building
