[Buildroot] [PATCH 1/5] libressl: new package

[Adam Duskett]

    Libressl is a fork of openssl from OpenSSL in 2014.  It's 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.

    The main source is libressl-portable, which "Includes the build scaffold
    and compatibility layer that builds portable LibreSSL from the OpenBSD
    source code."

    Before the build process can begin, autogen.sh must be ran manually,
    as it pulls from the upstream OpenBSD source which adds several
    directories to the source, along with several other steps necessary
    before building can begin. Setting LIBRESSL_AUTORECONF = YES fails
    with several "No such file or directory" errors as well.

    This package has been tested with the following architectures and c libraries:
    - armv4
    - aarch64
    - ppc
    - ppc64
    - ppc64le
    - x86_64
    - uClibc-ng
    - glibc 2.24
    - musl
