hotspot linux-sparc support has been pushed

[Matthias Klose]

trying to build this with jdk6,

 - openjdk/hotspot/build/linux/makefiles/sparc.make is missing, but
   available on jdk7.

 - the build needs -fPIC instead of -fpic (the latter leading to a link
   error).

 - openjdk/hotspot/src/os_cpu/linux_sparc/vm/os_linux_sparc.cpp
   lacks os::allocatable_physical_memory, leading to a link error.

 - sparc isn't detected as a valid architecture, only sparc64 is.

Attached are the patches which were used to build the openjdk-6 package in
Ubuntu intrepid.
