If N32 userland refers asm-mips/sigcontext.h, struct sigcontext cause

The kernel use 64-bit for sc_regs[0], and both N32/N64 userland
expects it was 64-bit. But size of 'long' on N32 is actually 32-bit.
So this definition make some confusion.
glibc has its own sigcontext.h and it uses 'unsigned long long' for
sc_regs, so no real problem with glibc.
Just out of curiosity, for what purpose does the glibc use sigcontext ?
