Hello!

openjdk-9 currently fails to build from source on Debian/sparc64 [1].

One of the reasons it fails is because of a misnamed header filename:

In file included from 
/<<PKGBUILDDIR>>/src/hotspot/src/share/vm/memory/allocation.inline.hpp:28:0,
                 from

error: atomic_linux_sparc.hpp: No such file or directory
 #include OS_CPU_HEADER(atomic)

While fixing this, I also discovered some other problems with the build on 
Debian/sparc64.

I'm attaching a set of three patches which address all the issues I have 
discovered with
openjdk-9 on Debian/sparc64 so far. They should apply to all builds on 64-bit 
Linux SPARC.

Please note, this is my first attempt ever trying to get patches into OpenJDK, 
so I will
definitely need a little guidance. I have already asked in the #openjdk channel 
and after
signing the OCA and sending it in, I was told to post my patches here. So here 
they are :).

Let's hope I can get them into the proper shape for getting them merged.

All patches are:

Thanks,
Adrian
