makefiles: fix linking of PIE code
PIE documentation:
:
https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html
http://lfs.osuosl.org/hlfs/view/unstable/glibc/chapter02/pie.html
suggest to suply -fPIE (or -fpie) with -pie
during executable compilation.
When -fPIC and -fPIE are used together - -fPIE wins
Drop usage of -DPIE - we are not using this flag anywhere
TODO: cleanup linking flags
