Build error when enable the CONFIG_FIT_SIGNATURE

For Developers
1

My platform is LS1046ardb and checkout to v18.06.1.
Now I want to do verified boot. So I modified the .config of uboot. Actually I turn on the needed configs, but error is happend at

CONFIG_FIT_SIGNATURE=y

I get the error "undefined reference to 'pthread_once'".
How to fix it? It seems the error in Makefile.

Here is the error:

I have fix this issue by modify the uboot source code.
In tools/Makefile, add -lpthread.

$(shell pkg-config --libs libssl libpthread libcrypto 2> /dev/null || echo "-lssl -lpthread -lcrypto")

Thanks for posting your solution. I just ran into this error building 18.06.4. Have you filed a bug with OpenWRT?

The problem is at building tools. Modify the file uboot-xxxx/tools/Makefile.
old: $(shell pkg-config --libs libssl libcrypto 2> /dev/null || echo "=lssl -lcrypto"
new: $(shell pkg-config --libs libssl libcrypto -lpthread 2> /dev/null || echo "=-lssl -lcrypto -lpthread"

No, I have not post the issue to Openwrt.
