[gnutls-devel] GnuTLS | Use soname instead of file name in fipshmac sections (!1675)

[Read-only notification of GnuTLS library development activities]

Daiki Ueno started a new discussion on lib/fipshmac.c: https://gitlab.com/gnutls/gnutls/-/merge_requests/1675#note_1195773632

By the way, it's also tempting to simplify `lib/fips.c` using `dl_iterate_phdr`; then we could omit the `dlopen`/`dlsym`/`dladdr` dance and soname check in configure altogether.
