[PATCH] AVR32: Fix sa_restorer when SA_ONSTACK is set

[Haavard Skinnemoen]

From: Haavard Skinnemoen <hskinnemoen at atmel.com>

I don't remember exactly why we decided to pick the caller's value of
sa_restorer when SA_ONSTACK is set, but it seems to break LTP's
sigaltstack testcase. Some users have reported problems with
sigaltstack as well; hopefully this will fix it.
