Add -lc++ -lm to the command line and it passes. These flags should not have to be passed manually.
Note, the Chrome OS chroot clang is fine.

Actually there not clang-7.0, only clang-7. Probably because there are no llvm-X.Y releases. This is causing the existing pattern matching and symlink generation part of cros_setup_toolchains script to fail.

The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/chromite/+/ae26814f310e3acfa6ab09ad78d1d40266613054 commit ae26814f310e3acfa6ab09ad78d1d40266613054 Author: Manoj Gupta <manojgupta@google.com> Date: Sat Apr 28 18:36:23 2018 cros_setup_toolchain: Fix clang++ invocation. Newer clang release do not use X.Y prefixes for clang binary, but just use a clang-X notation. This is breaking the pattern match in Clang wrapper symlink fixup. BUG= chromium:837889 TEST=Correct symlinks are created.
