(Failure to build from source)

When building lldb 9.0.0 on Clear Linux, with Python 3.7, lldb fails to build.

Configured as:
cmake -G 'Unix Makefiles' -DBUILD_SHARED_LIBS:BOOL=ON
-DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_SBINDIR=/usr/bin
-DCMAKE_INSTALL_LIBDIR=/usr/lib64 -DLIB_INSTALL_DIR=/usr/lib64 -DLIB_SUFFIX=64
-DCMAKE_AR=/usr/bin/gcc-ar -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DCMAKE_RANLIB=/usr/bin/gcc-ranlib ..  -DLLVM_HOST_TRIPLE=x86_64-generic-linux
-DLLVM_LIBDIR_SUFFIX=64 -DLLVM_LINK_LLVM_DYLIB:BOOL=ON
-DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python3

Build succeeds, but fails to install:
