Search prefix /usr before root prefix /
Commit "Find locally installed software first" made /usr/local the first prefix searched to be consistent with the Filesystem Hierarchy Standard: http://www.pathname.com/fhs/ The standard also implies that the root prefix "/" should not have any package or development files. The "/bin" and "/lib" directories should have only minimal contents to boot the system. No "/include" ever exists. This commit re-orders the search path prefix list from /usr/local / /usr to /usr/local /usr / to prefer package and development files over low-level system files. See issue #10136. On Cygwin /usr/lib == /lib and /usr/bin == /bin. This change also makes search results report locations as "/usr/..." instead of "/lib/...". See issue #10122.
