Linking error: libQt5Network.so: undefined reference to `EC_curve_nist2nid'

问题

I'm building my qt application and on a linking stage I'm getting the following problem:

/usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0/../../../../lib/libQt5Network.so: undefined reference to `EC_curve_nist2nid'
collect2: error: ld returned 1 exit status

I was not getting this problem before and I have a feeling that it is in some way related to system update (though nor qt nor openssl packages were updated).

My system is Arch Linux Qt 5.5.1 openssl 1.0.2.f-1

And btw the symbol is present in libcrypto:

nm /usr/lib/libcrypto.so -C |grep EC_curve_nist2nid
00000000000e6bb0 T EC_curve_nist2nid

In case it would be helpful:

stvad@stvadpc apps %ldd /usr/lib/libQt5Network.so  
...
        libssl.so.1.0.0 => /usr/lib/libssl.so.1.0.0 (0x00007fcb68e0c000)
        libcrypto.so.1.0.0 => /usr/lib/libcrypto.so.1.0.0 (0x00007fcb68994000)
...
