Current ucontext_t does not match with kernel's definition.  Also, on
N32 ABI, we can not use kernel's struct sigcontext since kernel's
sizeof(long) and user's sizeof(long) is differ.

For both data structure, just importing header files from recent glibc
fixes the mismatch.  So here is a patch importing sys/ucontext.h and
bits/sigcontext.t from glibc-2.5.
