icedtea/openjdk build for sparc-linux

[Matthias Klose]

Checked in Suns patches to build on sparc-linux, backported to IcedTea6. The
mauve testsuite results look the same like on x86 and amd64. Note that I only
tested on a 64bit kernel, running 32bit user space, so maybe some adjustments
are needed for 64bit user space.
