[exim] Exim with PCRE2

Hi,

I am trying to build exim with PCRE2 support. I am doing this via
debhelper. However it seems I still get some errors after modifing
pcre-config with pcre2-config and pcre.h with pcre2.h.

I've searched the internet and some information over IRC mentioned exim is
not supporitng pcre2 yet. Can you please let me know if this is the case or
not?

Thanks you!

Kind regards,
Andrei
