From 75f18de67e7bc7f1feb360eb4201a3c6d6773698 Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Thu, 21 Jun 2012 19:34:49 +0000 Subject: pkg-utils.mk: add utility functions find*clauses and notfirstword This patch adds a few utility functions to pkg-utils.mk. Functions finddirclauses and findfileclauses help in building a find command that skips a set of directories and performs operations on a set of files. This pattern can for example be used to keep certain files or directories from being stripped, or to remove certain files from a package installation. The notfirstword function is the inverse of the 'firstword' function in make: it returns all but the first word.
