Make.inc, deps/Makefile: rename HOST => XC_HOST.

This is a rather unfortunate Make variable name since
it is automatically defined in OS X shell sessions.
(Worse still, if you try to unset it, it crashes your
shell upon accessing that environment variable.)
srand: make integer seeding only depend on the *value* of the seed.

This guarantees that no matter what the type of an integer seed
used to seed the RNG, the same seed vector will result, depending
only on the value of seed given. This ensures identical behavior
on 32-bit and 64-bit systems if integer literals are used for
seeding. If you want more control over the seed vector, supply an
actual Vector{Uint32} of seed data.

This reverts commit 370f0334a3ad0e6c8c8e44a6e2c7ab041a960f67.
fallback: ~(n::Integer) = -n-1

In particular, this defines ~ for BigInts in a way that's
compatible with the behavior of fixed-size integer types.

fix #1866 (darwin gmp build failure)
use every bit of seed value. previously n and ~n gave the same seed.
GMP module: modularize BigInt and BigFloat functionality.

This is kind of broken since it can only be loaded when you
are in the julia build directory. Really, this should be moved
into a GMP module, but I didn't want to get too deep into a
yak shaving expedition before committing.

Also bump up to the latest GMP version number.
