Issue Description:

Facing following issues running lldb-Suite test cases while building Apple Swift 5 toolchain on PowerPC64LE.

Around 109 test cases fail with the same error message:-

*\<bound method SBProcess.Kill of \<lldb.SBProcess; proxy of \<Swig Object of type 'lldb::SBProcess ' at 0x3fff8e8d51b0> >>: success

Following is the detailed failure of one of the failing test cases:-

Iam invoking the toolchain and the tests using the following command:-

{{ ./swift/utils/build-toolchain srtbundle --test}}

I assume this creates a release build, where source files are compiled without any debug information.
So in that case the binaries(a.out and others) might not really help in debugging with lldb, hence the tests fail. Could this be the case here?

Looks like the tests are built with g option:

I tried manually debugging the test binary, and here is the output:-
