Simplify setfattr use by assuming GNU make

Browse Source 
* Makefile.in (PAXCTL_if_present, SETFATTR_if_present): New macros.
(emacs$(EXEEXT), temacs$(EXEEXT), bootstrap-emacs$(EXEEXT)): Use them.
Simplify by using GNU make rather than shell conditionals,
by using ln -f rather than rm -f followed by ln,
and by preferring $@ to spelling out the destination.
