Commit 82425427e5cfb547318e20e6e8ad23b77674996f in kudu's branch
refs/heads/master from Alexey Serbin

KUDU-3805 prefer using mold linker when available
This changelist enables using the mold linker [1] for building Kudu
and addresses KUDU-3614 as well.
With the mold linker, it was necessary to switch to using --exclude-libs
for gflags and glog libraries to avoid exporting their symbols.
It seems the mold linker doesn't recognize and interpret the *google::*
pattern the same way as a GNU ld-compatible linker does. With that,
I removed corresponding sections from src/kudu/client/symbols.map.
Maybe, we need to eventually switch to using --exclude-libs=ALL and
avoid using the --version-script provisions, but it's a separate story.

> The [mold linker|https://github.com/rui314/mold] is faster and uses less
> memory than standard GNU ld and LLVM's lld linkers. To reduce Kudu build
> times and memory usage during build, it makes sense to switch to the mold
