* Makeconfig (+link-pie): Indent.
|
||||
* Rules (binaries-pie): Define if $(have-fpie) and
|
||||
$(build-shared).
|
||||
(binaries-shared): Also filter out $(binaries-pie).
|
||||
($(addprefix $(objpfx),$(binaries-pie))): New rule.
|
||||
* nscd/Makefile (others-pie): Add nscd.
|
||||
(LDFLAGS-nscd): Set this instead of relro-LDFLAGS.
|
||||
($(objpfx)nscd): Remove command override.
|
||||
* login/Makefile (others-pie): Add pt_chown.
|
||||
($(objpfx)pt_chown): Remove command override.
|
||||
* elf/Makefile: Add PIE tests to tests and tests-pie variables and
|
||||
remove command overrides.
|
||||
|
||||
