From 41f677100e15f315f638774fbd055e497fc90069 Mon Sep 17 00:00:00 2001 From: Elliott Hughes Date: Sun, 15 Feb 2015 12:34:33 -0800 Subject: Export elfutils headers and lose the version number from the path. Having the version number in the path just means that diffs for updates are completely unusable. perf refers to libdw.h, libdwfl.h, and version.h as and so on, so we do still need to do some manual work there, but let's use symlinks rather than duplicating the header files.
