commit 27a451e3739d8331b9c180b0373b88ab6c382409
Author: Richard Levitte <levitte at openssl.org>
Date:   Tue Nov 15 09:56:20 2016 +0100

    On x86 machines where the compiler supports -m32, use 'linux-x86'
    
    The rationale is that the linux-x86 is the most likely config target
    to evolve and should therefore be chosen when possible, while
    linux-elf is mostly reserved for older Linux machines.

commit 7fbc0bfdd7a3c46bc7e36b191d11ab3853555a25
Author: Richard Levitte <levitte at openssl.org>
Date:   Tue Nov 15 09:53:01 2016 +0100

    Add a modern linux-x86 config target
    
    'linux-x86' is similar to 'linux-x86_64' but uses -m32 rather than -m64.
