Cross-compiling OpenSSL 1.1.1 - specifying toolchain

[lcaperici via openssl-users]

Trying to compile OpenSSL using Bootlin tool chains for ARMv5 UCLIBC found at 
https://toolchains.bootlin.com/

Does anyone have recent experience compiling OpenSSL 1.1.1 specifying alternate 
tool-chains?

What commands did you use?

Thanks
