(The upgrade of the ppc64le bot and D121257 have fixed compiler-rt failures. Tested by nemanjai.)
Default the option introduced in D113372 to ON to match all(?) major Linux
distros. This matches GCC and improves consistency with Android and linux-musl
which always default to PIE.
Note: CLANG_DEFAULT_PIE_ON_LINUX may be removed in the future.

Build System Changes
--------------------
+* CMake ``-DCLANG_DEFAULT_PIE_ON_LINUX=ON`` is now the default. This is used by
+ linux-gnu systems to decide whether ``-fPIE -pie`` is the default (instead of
+ ``-fno-pic -no-pie``). This matches GCC installations on many Linux distros.
+ Note: linux-android and linux-musl always default to ``-fPIE -pie``, ignoring
+ this variable. ``-DCLANG_DEFAULT_PIE_ON_LINUX`` may be removed in the future.
