I don't think it's worthwhile to add complexity to configure and the fat
machinery, and testing thereof, to make it flexible enough for that
usecase. In your case, you need it to be able to use an assembler
missing support for instructions added to the architecture 7.5 years
ago. Are there other usecases where more flexibility would be
beneficial?
I might consider it, if someone else wants to do the work, and it turns
out it doesn't get too messy.
To get it to work in your setting, I would suggest one of:
(i) Stick to --disable-assembler, to get something that works but is
slow (and unfortunately a performance regression since nettle-3.6).
(ii) Upgrade your assembler to a version that recognizes the sha
instructions (not sure which assembler you're using, I did ask,
when you reported the problem back in January, but I haven't seen
an answer). I would be a bit surprised if support for these
instructions is still missing in recent releases of Oracle's
development tools, if that's what you're using.

To be honest, high performance on the proprietary and somewhat obscure
Solaris operating system is not going to be a high priority to me, in
particular version 11.3 which is soon officially end of support (January
2024, according to wikipedia, curiously the same date as for the much
older Solaris 10). Correctness, which you'd get with
--disable-assembler, is considerably more important. I'm willing to help
getting Nettle to work on obscure and obsolete systems, as long as the
cost in added complexity is small.
