perl5.24: new port

[mojca (Mojca Miklavec)]

I'm adding a new subport for Perl 5.24, but it turned out that flags -Dccflags are problematic and -Accflags should be used instead (see #51330).

This means that we probably need to rebuild all older Perl versions as well (unless we only change flags for Perl 5.24). I'm confused because I don't understand the fact that perl5.22 -V still outputs -DPERL_DARWIN even though it probably doesn't use it during the build.

Some further minor changes were added to support installation of RC.

I would be grateful for wider testing before committing (and breaking) anything (including running the tests). I would commit 5.24, but I'm afraid of screwed something up in earlier versions.

Add perl5.24, change configure flags to use -Accflags=... rather than -Dccflags=...
