Comment (by chrisminett):

 I went through the PHP migration docs and changed those that were listed.
 The only one that appeared to require pkg-config as a build dependency was
 php-imap. Every one that I changed from standard I installed in trace mode
 without issue. I haven't installed every single core extension, but I'll
 do that now!
