[Buildroot] [PATCH v4 1/1] libressl: new package

Thu Jul 6 11:12:01 UTC 2017

Libressl is a fork of openssl from OpenSSL in 2014.  Its goal is to
modernize the OpenSSL codebase, improve security, and apply best
practice development processes.

Right now, libressl is API compatible with OpenSSL 1.0.1, but does not
yet include all new APIs from OpenSSL 1.0.2 and later.

Changes v3 -> v4:
  - Removed libssl virtual package. (Arnout)
  - Re-added Config.in (Arnout)
  - Moved libressl to right before OpenSSL in package/config.in with
    a explanation as to why it breaks alphabetical ordering. (Arnout)
  - Added depends on !BR2_PACKAGE_OPENSSL in Config.in (Arnout)
  - Changed capitalized letters to lowercase in libressl.mk (Arnout)
  - Removed libssl specific syntax in Config.in and libressl.mk
  - Added LIBRESSL_INSTALL_TARGET_CMDS in libressl.mk
    Without this, all the header files and man-pages are installed to the
    target filing system.  This is undesired behavior. Instead, running
    “install-exec” will only install the libraries to the target filing system.

Changes v2 -> v3:
  - Moved this patch to the end of the series. (Thomas)
  - Removed Config.in thanks to the new libssl. (Thomas)
  - Dropped host-autotools-package for now. (Arnout)

Changes v1 -> v2:
  - Changed from github to openbsd ftp. This is a all-in-one tarball
    that negates having to use the POST_PATCH_HOOKS. (Thomas)
  - Added 0001-remove-test-z-DESTDIR-from-ltmain.patch, this allows
    ltmain.sh to be patched with buildroot-libtool-v2.4.patch, which
    removes the need for a call to autogen.sh.
  - Changed sha256sum to reflect new tarball.
  - Changed Locally computed to openbsd ftp hash list in hash file. (Arnout)
  - Added DEVELOPERS changes to this patch. (Thomas)
  - Fixed formatting in commit message. (Thomas)
  - Removed "and scripts" from Config.in (Arnout)
