[COMMITTED PATCH] Move rules for Linux-specific pldd program to Linux-specific Makefile.

[Roland McGrath <roland at hack dot frob dot com>]

pldd.c is built around core assumptions of Linux-specific facilities
(ptrace and its exact use, /proc/PID/* files behaving very exact ways).
It doesn't make sense to try to build it on non-Linux configurations.

I didn't move the source files themselves because there is no special
benefit to doing so.  Perhaps someday someone will factor out the
Linux-specific parts and make it possible to implement non-Linux support
for pldd.


Thanks,
Roland


	* elf/Makefile (others, install-bin): Remove pldd.
	(pldd-modules): Variable removed.
	($(objpfx)pldd): Target removed.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir) = elf]
	(others, install-bin): Append pldd here.
	($(objpfx)pldd): New target.
