This certainly looks like a miscompile of OpenSSL.  Can you please
provide the numbers printed right after SHA1_Init()?  Are they the same
or also different for the two builds?

I'd guess that OpenSSL somehow got configured for a wrong size of "long"
or/and endianness.  Since you were cross-compiling, you couldn't even
"make check" it easily.
