+	 * Sigh.  Somebody actually attempted to use freedesktop.org pkg-config's broken sysroot support,
+	 * which was written by somebody who did not understand how sysroots are supposed to work.  This
+	 * results in an incorrect path being built as the sysroot will be prepended twice, once explicitly,
+	 * and once by variable expansion (the pkgconf approach).  We could simply make ${pc_sysrootdir} blank,
+	 * but sometimes it is necessary to know the explicit sysroot path for other reasons, so we can't really
+	 * do that.
+	 *
+	 * As a result, we check to see if ${pc_sysrootdir} is prepended as a duplicate, and if so, remove the
+	 * prepend.  This allows us to handle both our approach and the broken freedesktop.org implementation's
+	 * approach.  Because a path can be shorter than ${pc_sysrootdir}, we do some checks first to ensure it's
+	 * safe to skip ahead in the string to scan for our sysroot dir.
+	 *
+	 * Finally, we call pkgconf_path_relocate() to clean the path of spurious elements.
