(PA-4718) Updates for Solaris and agent-runtime-main

[cthorn42]

This PR updates Solaris on agent-runtime-main to:

• Build libffi, with gmake
• Build Ruby 3.2.2 with OpenCSW gcc
• Configure rubygem-ffi, but still expected to fail. rubygem-ffi will be fixed at a later point
• Also installs a new GCC and autotools as part of the image.

It looks like you may have to update master and rebase but otherwise LGTM 👍

Looks to be an empty merge commit in your feature branch. I'd try rebasing on upstream, which should drop the extra merge commit:

git fetch upstream
git rebase 1a77733 --onto upstream/master
git push -f origin HEAD

Due to the order of these if's, we no longer override PATH when compiling agent-runtime-7.x on cross compiled linux or solaris:

$ bundle exec rake vanagon:component_diff -- -P agent-runtime-7.x -p solaris-10-sparc --from HEAD^ --to HEAD
...

Project agent-runtime-7.x

Platform name: solaris-10-sparc
    Component 'rubygem-ffi'
        Field: environment
        --------------------
        - GEM_HOME=/opt/puppetlabs/puppet/lib/ruby/gems/2.7.0 GEM_PATH=/opt/puppetlabs/puppet/lib/ruby/gems/2.7.0 RUBYLIB=/opt/puppetlabs/puppet/lib/ruby/vendor_ruby:$(RUBYLIB) MAKE=/opt/csw/bin/gmake PATH=/opt/pl-build-tools/bin:/opt/csw/bin:$(PATH)

Maybe something like?

Suggested change

	if platform.is_cross_compiled_linux? || platform.is_solaris?
	if platform.is_cross_compiled_linux?
	pkg.environment "PATH", "/opt/pl-build-tools/bin:$(PATH)"
	elsif platform.is_solaris?
	if settings[:runtime_project] == 'agent-runtime-main'
	pkg.environment "PATH", "/opt/csw/bin:/opt/pl-build-tools/bin:$(PATH)"

$ bundle exec rake vanagon:component_diff -- -P agent-runtime-main -p all --from HEAD^ --to HEAD  | grep 'Platform name'
Platform name: solaris-11-sparc
Platform name: sles-12-ppc64le
Platform name: solaris-10-i386
Platform name: el-7-ppc64le
Platform name: el-7-ppc64
Platform name: solaris-11-i386

Of those, {el-7,sles-12}-ppc* are not actually supported and can be ignored (and will be removed in other tickets)
