Thanks, that did the trick! Should I add this information to
https://llvm.org/viewvc/llvm-project/lldb/trunk/www/ and submit a
review on Phabricator?

For those who run into this message in the future, here's the exact
commands I ran to get gdbserver working:

wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
sudo apt-add-repository "deb http://apt.llvm.org/xenial/
llvm-toolchain-xenial-5.0 main"
sudo apt-get update
sudo apt-get -y install lldb-5.0 gdbserver
wget https://llvm.org/svn/llvm-project/lldb/trunk/examples/python/x86_64_linux_target_definition.py
# In another terminal run: gdbserver localhost:4444 /bin/date
lldb-5.0 /bin/date
settings set plugin.process.gdb-remote.target-definition-file
./x86_64_linux_target_definition.py
gdb-remote localhost:4444
