-Subject: update-patchelf
-MIME-Version: 1.0
-Content-Type: text/plain; charset="utf-8"
-Content-Transfer-Encoding: 8bit
-
-Update patchelf to current git version
-
-The current version fixes a bug which broke the ability to strip
-binaries with debug symbols:
-https://github.com/NixOS/patchelf/pull/117
-
-With the former version of patchelf, I would get "not enough room for
-program headers, try linking with -N" when trying to strip the binaries.
-
-This patch brings patchelf in sync with the commit
-27ffe8ae871e7a186018d66020ef3f6162c12c69 of patchelf's git
-repository.
-
-Also update patchelf's build process to match the logic in upstream's
-automake files (thanks to Frédéric Bonnard for the patch to properly use
-getconf PAGESIZE).
-
-Bug: https://bugreports.qt.io/browse/PYSIDE-740
-Last-Update: 2018-07-09
