reallocarray has been added to glibc relatively recently (version 2.26,
from 2017) and apparently not all users run new enough glibc. Moreover,
reallocarray is not available with uclibc-ng. So use realloc if
reallocarray is not available to avoid the following build failure
raised since commit 891b78e9e8:
/home/giuliobenetti/autobuild/run/instance-3/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/10.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: src/sae.o: in function `sae_rx_authenticate':
sae.c:(.text+0xd74): undefined reference to `reallocarray'
Fixes:
