Some small fixes that actually make the build pass. I have no idea why this is working for Oracle.

The first failure is:

cthalinger@vm-macbuild:~/jtreg-upstream/make$ sh build-all.sh /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home
build-all.sh: line 119: sha1sum: command not found

After fixing the above error we see errors when sha1sum is used:

shasum: standard input: no properly formatted SHA1 checksum lines found
