If I understand correctly, mariadb packages on OpenBSD machine (5.3, amd64) should work fine, only the client has these posix issues on platforms other than i386 or amd64.
and as far as I can see the integration of mariadb in OpenBSD on archs other than i386 or amd64 depends on the implementation of that assembler code. Having these in mind what is the roadmap of integrating mariadb in OpenBSD?

It won't affect your use of the server on Linux x86/x86_64. The relevant code is written in assembler for amd64/i386 and for other arches it falls back to using ucontext.h functions specified by an old version of posix which were never implemented on OpenBSD. They were marked 'obsokescent' in newer posix due to a dependency on an obsolescent C language feature (see 'rationale' in http://pubs.opengroup.org/onlinepubs/009695399/functions/makecontext.html) so can't be used in strictly posix-conforming software. They aren't widely used (I've only seen it in mariadb and powerdns-recursor) and unlikely to be added to OpenBSD. (For some uses, boost's context library might be an alternative, though I'm unsure about arch support).
