This patch adds the complete Mono implementation. This patch builds
both the native and managed parts.

Chengelog:

* Fixing default mono version with select in Config.in
* Rewriting library selection logic in mono.mk

[Thomas:

  - Merge mono-managed and mono-native as a single package. The
    mono-managed stuff is done by the host variant of the mono
    package, while the mono-native stuff is done as the target variant
    of the mono package.

  - Introduce a BR2_PACKAGE_MONO_ARCH_SUPPORTS blind Config.in option
    to make sure the IPv6 related comment is not displayed when the
    architecture being used anyway doesn't support Mono.

  - Add a patch to Mono to fix the C library path when uClibc and Musl
    is used. This is a better approach than the
    POST_INSTALL_TARGET_HOOKS because this approach can potentially be
    submitted upstreamed, which ultimately allows to simplify the
    Buildroot package.

  - Depend on a 'monolite' package, and use it instead of letting Mono
    download Monolite by itself, which circumvents Buildroot's
    download infrastructure.

  - Move the installation of Mono libraries to the target Mono
    package, as a POST_INSTALL_TARGET_HOOKS.]

[Angelo:

  - Bump to the latest Mono version 3.10.0

  - Add selection for .Net runtime compilation and installation in
    target.]

+Adjust libc.so path depending on C library being used
+
+By default, on Linux systems, Mono assumes that the C library is
+libc.so.6. While this is true for glibc, it is not true for uClibc and
+Musl based systems. This patch adds support for such systems.
