clang-lto fixes for v5.12-rc1

- Fix parisc build for ftrace vs mcount (Sami Tolvanen)
- Move .thinlto-cache remove to "clean" from "distclean" (Masahiro Yamada)
kbuild: Move .thinlto-cache removal to 'make clean'

Instead of 'make distclean', 'make clean' should remove build artifacts
unneeded by external module builds. Obviously, you do not need to keep
this directory.
