Sorry for the late reply. I just tried a fresh build and it still fails with

[..]/src/contrib/bearssl/src/rsa/rsa_i62_keygen.c:43:22: error: a function
declaration without a prototype is deprecated in all versions of C [-Werror=
,-Wstrict-prototypes]
  br_rsa_i62_keygen_get()

Did you see any other possibilty to fix this?
