grumble (IBM makes interesting compilers - though I suppose getting
Linux to build with an ANSI C compiler would be a lot of work).

something like that - the people involved will tend to just copy from
existing Linux ports rather than absorb much from the existing os390
(and where it differs from their expectations, it'll be regarded as
a bug - I just spent a few nights doing a proper port of a utility
whose most recent maintainer I read some comments to the effect that
well, he knows this particular feature isn't POSIX, but all of the
platforms he's using do it the way he he wanted to use it, and he
couldn't be bothered with addressing the issue POSIX cautions about).

So a Linux/390 would be what - another 32-bit port (or is that 64) with a
few customizations made to accommodate different peripherals visible to
the applications, and a fair amount of kernel tweaks to fit with whatever
memory management hooks are needed.
