linux-libc-headers 2.6.8.0

Available at http://ep09.pld-linux.org/~mmazur/linux-libc-headers/
Changes:
- updated to 2.6.8
- readded ucontext.h - originally thought glibc could handle that, but doesn't seem that way (newest hddtemp builds)
- readded unaligned.h (and cleaned it up) - reiserfsprogs' developers found a use for it in userland (newest reiserfsprogs builds)
- added and cleaned up (more or less) the sh64 arch
- tried to add missing arm subarch - needs testing I guess
- minor fixes (some ia64 and x86_64 userland conflicts)

This release should have been here a day or two ago weren't it for Murphy's laws (the machine that I use for llh development 'broke' yesterday... after 4 months of uptime :).

Enjoy.

In the year eighty five ten
God is gonna shake his mighty head
He'll either say,
"I'm pleased where man has been"
Or tear it down, and start again
