My understanding is that:

> meta/recipes-support/libpcre/libpcre_8.43.bb:PROVIDES += "pcre"

means "I provide both "libpcre" as well as "pcre". I am assuming that
PROVIDES = "${PN}" is already set by a core BitBake rule somewhere.
(Didn't check...)

So I think it might be harmful to replace it with "=", as it would no
longer provide libpcre.
