Seem to be the case on Solaris 11.3

configure:19499: checking for arc4random_buf
configure:19499: gcc -o conftest -O2 -D_FORTIFY_SOURCE=2 -I/opt/pkg/include -I/opt/pkg/include -L/opt/pkg/lib -Wl,-R/opt/pkg/lib conftest.c -lsocket  >&5
Undefined                       first referenced
 symbol                             in file
arc4random_buf                      /var/tmp//ccCMa4jI.o
ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status
configure:19499: $? = 1

I believe on Solaris 11.4 arc4random_buf is available.
