problems compiling the latest openssl v1.1.1m, linux

Question

I've downloaded openssl-1.1.1m, and have gotten stuck compiling it on my GNU/Linux system. ./config shared make

(lots of stuff)
${LDCMD:-gcc} -Wa,--noexecstack -Wall -O3

./libcrypto.so: undefined reference to pthread_atfork' collect2: ld returned 1 exit status make[1]: *** [apps/openssl] Error 1 make[1]: Leaving directory /volume1/@config/openssl-1.1.1m' make: *** [all] Error 2

I've been reading around, and I moved -pthread to the end (as seen above), tried -lpthread, tried both, but those options provide the same result. Anyone with suggestions? One challenge, I'm stuck with gcc 3.4.6.
