I don't know if this is helpful.
I can't comment on sparc64, but we - the x86-64 team - do a x86-64-elf
crosscompilation on a x86 host and this seems to work. I have compiled
binutils, gcc and glibc just last weekend. I didn't actually try running
the binaries, but PR912 says it dies during the buildprocess, so at least
the problem would have changed.
