In general I think we should trust tuples *less* - it should be possible
to configure glibc with the same tuple as used for GCC (so, for example,
i686-*-linux-gnu and x86_64-*-linux-gnu should both work for building both
32-bit and 64-bit glibc - much like for MIPS we examine the value of
_MIPS_SIM to determine the ABI being built for). (I also think all cases
that can use the same tuple with GCC should install the same headers.)
