In the meantime I figured out that I only had a link to an outdated
(and probably removed) file on TI's web server, the site
    http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSPGCC/latest/index_FDS.html
still works and provides working links to a newer version of gcc, so I
was able to proceed with testing msp430 as well.

After installing gcc 8.3.0 with newlib 2.4.0 (the ones for which they
provide patches inside msp430-gcc-8.3.0.16-source-patches.tar.bz2) in
the same way that got me the spec files installed for arm, those same
spec files in fact seem to be missing for msp430-elf-gcc.

I don't quite remember where I got these instructions from. I was
definitely following a few tutorials in the past to get me started
with msp430 and some arm chips, but I'm not sure if the requirement to
specify the spec file came from one of the tutorials for arm, or maybe
random notes from internet about how to test msp430 when I tried to
update the msp430 toolchain inside our package manager, like for
example:
    https://gist.github.com/0/631c9006a672458eaa48

Bottomline: I'm perfectly happy at the moment that I hopefully got the
arm toolchain fixed (which was both reported by two of our users, plus
me when I needed to do something with arm), while I'm not yet sure if
I actually need it for msp430, and it's unlikely that I'll soon have
time to play with msp430 boards again. In short: I'm probably happy
until the next user complains. (I don't know much about
cross-compilers or msp430, so I cannot argue whether the spec files
need to be added back or not.)
