Bug#945445: lldb-8: incorrect python path output by "lldb-8 -P"

[Ximin Luo]

Package: lldb-8
Version: 1:8.0.1-4
Severity: normal

Dear Maintainer,

lldb -P is supposed to print the path to the python lldb module. This does not work
in Debian, the path was not overridden correctly in the packaging:

$ lldb-8 -P
/usr/lib/x86_64-linux-gnu/python3.7/site-packages
$ ls -la $(lldb-8 -P)
ls: cannot access '/usr/lib/x86_64-linux-gnu/python3.7/site-packages': No such file or directory
exit code 2
$ dpkg -L python3-lldb-8
[..]
/usr/lib/llvm-8/lib/python3.7/site-packages/lldb
[..]

The fix is to override "lldb-8 -P" so it outputs /usr/lib/llvm-8/lib/python3.7/site-packages

This will make it easier to package rust-lldb as well.
