Linux/s390x support for Firebird 2.1.2

Dan HorĂ¡k wrote on firebird devel list:
I am a Fedora and Red Hat Enterprise Linux developer and we are now
porting whole Fedora package collection to the s390x (IBM System z a.k.a
mainframe) architecture. The official sources for Firebird (in version
2.1.2) didn’t support this architecture, so I have prepared a patch that
adds this support. Please let me know what else should I do to get the
support accepted into the official source tree.

the patch was uploaded to
