Subject: [PATCH] Fix linking against hostapd with LTO
When running LTO on wolfssl the ecc_map() function is removed from the
binary by GCC 8.4.0. This function is used by multiple functions from
the crypto_wolfssl.c implementation of hostapd master.
Fixes: 780e8a4619b6 ("Fixes for building `--enable-wpas=small` with WPA Supplicant v2.7.")
