hostapd does not support mesh, so I'm assuming you are talking about
using wpa_supplicant with mesh (CONFIG_MESH=y) and SAE (CONFIG_SAE=y)

I replaced the direct OpenSSL calls in SAE implementations five years
ago with crypto wrappers:
In other words, if someone is willing to work on implementing those
crypto_*() wrapper functions for various small crypto libraries, SAE
could be built with other libraries than OpenSSL.

Mesh (802.11s) does not use SSL at all. It uses SAE for the secure
network case and that requires certain crypto/FFC/ECC support from the
crypto library. Using mesh without SAE (i.e., just open network) should
work without such conditions, but anyway, I'd rather focus on getting
small implementations of crypto functionality working with SAE.
