LINKS: use stat -qf '%d %i' $l to read the device & inode # of the source and target (and rely upon a non-zero exit value to indicate a missing file), instead instead of unconditionally installing the link. SYMLINKS: use stat -qf '%Y' $l to read a symlink's target (and rely upon a non-zero exit value to indicate a missing file or non-symlink), instead of test -h $l && ls -ld $l | awk '{print $NF}' , since the former is quicker and more concise. This resolves PR toolchain/16885 from David Laight.

Add a pile of missing .PHONYs.

Improve readability and reduce redundant redundancy in share/mk; add some descriptive comments. The guts of hostprog, lib, and prog are mostly unchanged; this will be done in another pass. Make several things work properly with UNPRIVILEGED set, and make the install-time "cmp" logic work for MANZ. Also reimplement INCS{DIR,NAME}_foo (requested by wiz) in a backwards compatible way. Reviewed by christos.

##### Install rules
make(1) specifies, regarding :: targets: Sources for a target do not accumulate over dependency lines when this operator is used. An unstated implication of this is that when parallel builds are done, each separate instance of the target can be scheduled independantly. As a result, the linksinstall target with commands could be executed too early during a parallel build since they didn't actually have a dependancy on "realinstall". To fix this, correct the linksinstall:: realinstall dependancy by eliminating the command-less linksinstall target, and moving the dependancy to the other linksinstall target.
