It still does not work, but I think I already get glibc cross compiled.
Next: gcc and g++, and set some setup script hooks on stdenvCross.
It took quite enough hours for this commit.

My idea is to provide special stdenv expressions that will contain in the path
additional cross compilers. As most expressions for programs accept a stdenv parameter,
we could substitute this parameter with the special stdenv, which will have a
generic builder that attempts the usual "--target=..." and can additionally
have an env variable like "cross" with the target architecture set.
So, finally we could have additional expressions like this:
bashRealArm = makeOverridable (import ../shells/bash) {
inherit fetchurl bison;
stdenv = stdenvCross "armv5tel-unknown-linux-gnueabi";
};
Meanwhile it does not work - I still cannot get the cross-gcc to build.
I think it does not fill the previous expressions with a lot of noise, so I
think it may be a good path to follow.
I only touched some files of the current stdenv: gcc-4.3, kernel headers
2.6.28, glibc 2.9, ...
I tried to use the gcc-cross-wrapper, that may be very outdated. Maybe I will
update it, or update the gcc-wrapper expression to make it fit the cross tools,
but meanwhile I even cannot build gcc, so I have not tested the wrapper.
This new idea on cross compiling is not similar to that of the
nixpkgs/branches/cross-compilation, which mostly added bare new expressions for
anything to be cross compiled, if I understood it correctly.
I cared not to break anything of the usual stdenv in all this work.

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.

Redland's use of the pre-processor symbol SQLITE_API collides with a
symbol of the same name in sqlite 3.6.19. Patching the source code to
use REDLAND_SQLITE_API instead works around the problem.

Sqlite has a build mode called "amalgamation" that gathers all 90+ source code
files into a single sqlite3.c file before compiling the library. Building
sqlite this way reportedly gives a 5-10% performance gain because the compiler
can perform more sophisticated optimizations.

The new version requires Tcl at build time in order to construct sqlite3.h,
even when the --without-tcl option is passed to configure. That feels odd
because the sqlite web site does advertise "no dependencies", but then it's
probably not a big deal either. The build of the Tcl plugin for sqlite is still
disabled, so there is no run-time dependency.

propagatedBuildInputs, because those inputs are required by the *.pc
or *.la files of the package:
- If a *.pc file references a non-propagated input, then Gnome
packages have the bad tendency to silently ignore this problem in
configure scripts - the failure of a command like `pkg-config
--cflags foo' will be ignored if a dependency of foo.pc is
missing, so no flags will be added, and the build will fail later
on a missing header or library.
- If a *.la file references a non-propagated input, the build will
also fail, because Libtool will add library dependencies that it
cannot find. (Arguably *.la files should never reference packages
that aren't in the corresponding *.pc file, but they do it
anyway).
By setting the propagatedBuildInputs properly, it should be possible
to get rid of all the NIX_CFLAGS_COMPILE / NIX_LDFLAGS hacks in the
Gnome expressions.
