If I start:
```/usr/bin/lldb-server platform --listen '*:10000' --server```
then I get `Launch: invalid host:port specification: '[192.168.64.5]'`
but if I start:
```lldb-server platform --listen '*:10000' --server```
then everything works and I can debug without any problems.
```
$ which lldb-server
/usr/bin/lldb-server
```
In lldb I run:
`command script import test.py`

The code that is looking for the "support exe dir" is finding the wrong dir, see these two runs with logging enabled:
```
...
distribution id command returned "Distributor ID: Ubuntu
"
distribution id set to "ubuntu"
GDBRemoteCommunication::StartDebugserverProcess(url="" port=0)
shlib dir -> `/usr/bin/`
HostInfo::ComputePathRelativeToLibrary() attempting to derive the path /bin relative to liblldb install path: /usr/bin
HostInfo::ComputePathRelativeToLibrary() derived the path as: /usr/bin
support exe dir -> `/usr/bin/`
GDBRemoteCommunication::StartDebugserverProcess() could not find gdb-remote stub exe ''
GDBRemoteCommunication::StartDebugserverProcess() failed: unable to locate lldb-server-15.0.7
error: lost connection
lldb-server exiting...
```
vs.
```
