--- Comment #1 from Fangrui Song <i at maskray.me> ---
This is invalid. -fPIE is a compilation option while -pie is a driver option
affecting linking. -fPIE does not imply -pie in GCC.

What you want is something similar to GCC's configure-time --enable-default-pie
(introduced in GCC 6:
https://gcc.gnu.org/git/?p=gcc.git&a=commit;h=428b381275bc95032274440f02d7719225de2c17)

Some folks had the same question
http://lists.llvm.org/pipermail/cfe-dev/2020-June/065684.html but no decision
is made whether we should do it (personally I do not favor the idea much as it
just made the default behavior different on different distributions where the
distros can just provide default CFLAGS/LDFLAGS).
