Commit 986f361946 started to use
<nix/fetchurl.nix> to "download" the bootstrap binaries from the
Nixpkgs tree, using the file:/// scheme. This has really bad
consequences:
* It makes any derivation depend on the path of the Nixpkgs tree. So
evaluating a package will produce a different .drv file when run
from different locations. No wonder Hydra evaluation has been so
slow lately: for every Nixpkgs evaluation, it had to create tens of
thousands of .drv files, even if nothing had changed.
* It requires the builder to have file system access to the Nixpkgs
tree. So if your tree is in your home directory, the stdenv
bootstrap would probably fail.
So now the binaries are downloaded from tarballs.nixos.org.
Also dropped PowerPC "support".
Since nix-1.4, nix's corepkgs contain a fetchurl suitable for
downloading the bootstrap binaries. Doing this will allow us to have a
nixpkgs with no in-tree binaries without breaking the purity of the
bootstrap (though for now, they are fetched in-tree until the binaries
are added to nixos.org somewhere). As an additional small benefit, the
in-tree binaries do not have to be hashed on every instantiation as they
do now.
The fetchurl in nix-1.2 and 1.3 isn't able to make binaries executable,
so it can't be used for this case. In that case, attempting to build the
bootstrap will show a message asking the user to manually download each
file and add it to the store with nix-store --add (but the hash is
ultimately the same, of course).

we can't build easily with them gcc-4.4 natively, because of a bug in the ld of the
previous bootstrap-tools.
I updated the unpack script to include the new gcc-4.4 libraries *ppl*.so in patchelfing.

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.
