Thomas Weißschuh 91748d50c7 linux-user/mips/o32: Drop sa_restorer functionality ...

The Linux kernel dropped support for sa_restorer on O32 MIPS in the
release 2.5.48 because it was unused. See the comment in
arch/mips/include/uapi/asm/signal.h.

Applications using the kernels UAPI headers will not reserve enough
space for qemu-user to copy the sigaction.sa_restorer field to.
Unrelated data may be overwritten.

Align qemu-user with the kernel by also dropping sa_restorer support.
