It's only partially about whether libxml2 is portable enough. A person
building Postgres might also have legitimate concerns about how bug-free
and/or secure it is. We've already spent nontrivial amounts of time
working around libxml bugs; and as for security, google shows at least
four CVEs against libxml2 in the past two years, so it's not a
negligible risk. I can entirely see people choosing to build without it.
