To follow up with a bit more detail
The version of OpenSSL is 1.0.2e.
The exact steps inside of my Linux environment that I take are
1) log in as su.
2) run "make clean"
3) run "sh config zlib"
the last line logged from this command is
"Configured for linux-elf"
4) run "make"
the make gets as far as

it does make it through build bntest.o, ectest.o , ecdsatest,o,
ecdhtest.o, and ideatest.o
