Here's what pkg-config --static tells me on my system:

-lssl -lcrypto -ldl -pthread

So I use this for OPENSSL_LIBS, while explicitly requesting the static .a
libs (on the assumption that only openssl should be linked statically, not
all libs):

./configure --disable-all --with-openssl OPENSSL_LIBS="-l:libssl.a
-l:libcrypto.a -ldl -pthread"

configure passes, but then during linking I get:

/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/8/../../../x86_64-linux-gnu/libcrypto.a(threads_pthread.o):
undefined reference to symbol 'pthread_rwlock_wrlock@@GLIBC_2.2.5'

It looks like the "-pthread" flag gets stripped. Then I tried:

./configure --disable-all --with-openssl OPENSSL_LIBS="-l:libssl.a
-l:libcrypto.a -ldl" CFLAGS="-pthread"

This compiles successfully.

The fact that "-pthread" gets stripped from LIBS might be a bug.

Hope this helps,
Nikita
