This turned out to be relatively straightforward.  Two fixes:
ghc-asm.lprl needs slight modifications for new versions of gcc on
sparc-*-linux, and the dynamic linker also needs to have USE_MMAP
enabled due to needing to execute dynamically allocated memory.

I've made these fixes in the HEAD, and also merged them into the 6.2
branch.  William: there's a fixed tree in /mnt/dm0/simonmar/ghc-6.2.2 on
your sparc64 box.
