Linux 6.5 broke iwd

Hi Herbert,

Looks like something in Linux 6.5 broke ell TLS unit tests (and thus likely 
WPA-Enterprise support).  I tried a git bisect and could narrow it down to a 
general area.  The last good commit was:

commit 6cb8815f41a966b217c0d9826c592254d72dcc31

     crypto: sig - Add interface for sign/verify

     Split out the sign/verify functionality from the existing akcipher
     interface.  Most algorithms in akcipher either support encryption
     and decryption, or signing and verify.  Only one supports both.

     As a signature algorithm may not support encryption at all, these
     two should be spearated.

     For now sig is simply a wrapper around akcipher as all algorithms
     remain unchanged.  This is a first step and allows users to start
     allocating sig instead of akcipher.

Narrowing down further didn't work due to:
/usr/bin/ld: crypto/asymmetric_keys/x509_public_key.o: in function 
`x509_get_sig_params':
x509_public_key.c:(.text+0x363): undefined reference to `sm2_compute_z_digest'
collect2: error: ld returned 1 exit status
