Ruby makes use of the lesser known DLDFLAGS to compose flags passed to
the linker. Since DLDFLAGS is composed of arch, ldflags and dldflags
instead of overwriting DLDFLAGS we drop the correct flags into
dldflags. (lowercase vs uppercase)

This will avoid the following QA warnings, such as:
No GNU_HASH in the elf binary: './tmp/work/core2-64-overc-linux/ruby-shadow/2.4.1-r0/packages-split/ruby-shadow/usr/lib64/ruby/gems/2.2.0/gems/ruby-shadow-2.4.1/lib/shadow.so'

The error appears as follows:

ERROR: Failure expanding variable RUBY_GEM_VERSION, expression was
${@get_rubygemsversion("build/tmp/sysroots/x86_64-linux/usr/bin")}
which triggered exception TypeError: can't use a string pattern on
a bytes-like object

Adding an explicit utf-8 decode makes it work again.

Prior to this commit it is not possible to cross build a ruby gem.  In
fact even on the x86 system the object files for the native gem are
generated with the wrong compiler (the host compiler instead of the
cross compiler).

A better way to fix this in the future would be to use only gems that
supported cross compile tool called rake.  For now the bbclass can
modify the extconf.rb just before creating the gem and insert some
code into the Makefile so as to honor the cross compile environment.

In commit 1aa30310

 [puppet: move to
base layer] we made puppet available to all sub-layers but since we
didn't move the required ruby.bbclass we couldn't actually use it
without using meta-openstack. Complete the move by moving the
ruby.bbclass to the base layer. At some point I think we still want to
remove ruby.bbclass from meta-cloud-services completely and use
meta-ruby, but we will do that at another time.

In order to build chef we create a new ruby.bbclass to handle
packaging ruby gems.

The gem install technique we make use of avoids dependency issues
which are not easily worked around yet care must be taken to ensure
runtime dependencies are properly listed.
