installer misidentifies illumos OS

I'm directing this here because https://tug.org/texlive/lists.html says 
this list is for bug reports. Apologies if there's a better place, or if 
this is a known issue: I searched the archive for the obvious keywords 
and didn't see any immediately relevant subject line.

The TeXLive 2026 installer (I have not tested earlier) identifies 
OpenIndiana, an illumos distribution, on x86_64 as i386-solaris and 
therefore selects those binaries to install. (Presumably this is because 
on OI "uname -s" or whatever equivalent test still returns "SunOS"?) The 
installation completes without error, but then the binaries fail to run. 
I see the same behavior with forcing the installer to use x86_64-solaris 
instead. The archives of the OpenIndiana mailing lists suggest that this 
may be because at some point in the last few years the prebuilt Solaris 
binaries began to be built on Solaris 11, and illumos is closer to 
Solaris 10.

So as I see it, there are two issues:
- OS misidentification results in a nonfunctional installation -- 
probably the installer should just do whatever it does for other 
platforms where prebuilt binaries aren't available
- probably much less pressing, CPU misidentification of i386 vs x86_64
