I'm working on Solaris 11.3 i86pc. I'm building the Nettle 3.5.1 release tarball.

configure: summary of build options:

Sun provides an old GCC. The compiler supports AES-NI, but it lacks SHA.

$ gcc --version
gcc (GCC) 4.8.2

Note that the error messages are from the assembler, not gcc. You're using Solaris' assembler, or GNU binutils?

The best option is to upgrade to an assembler supporting these instructions. The easy option is to drop --eable-fat from the confgure arguments.

There are other options, e.g., pre-assembling these instructions and replacing them with .byte sequences in the .asm file, or additional configure checks to test assembler features and conditionally disable this code. But I'd prefer to not go that way.
