-fPIC is used at the compile step to produce code in the .o files that
_can_ be linked in a position-independent executable (or shared
library).  But whether the output executable is position dependent or
not ultimately depends on the link step, whether -pie or -no-pie is
passed.  And if neither are passed, it depends on the default setting of
the linker.  That default setting was "no pie", but has changed to "pie"
pretty much everywhere in the last few years.
