If a build expressions has set "enableParallelBuilding = true", then the
generic builder may utilize more than one CPU core to build that particular
expression. This feature works out of the box for GNU Make. Expressions that
use other build drivers like Boost.Jam or SCons have to specify appropriate
flags such as "-j${NIX_BUILD_CORES}" themselves.

- Stating better the guile dependencies (native/host) for guile to build
- Fixing cross-linking, through --rpath-link (ld(1) explains well about it
- Made gcc call the linker and the assembler through the gcc wrapper instead of
directly. I thought this was the source of missing -rpath's, but the source
of the problem ended up being the lack of --rpath-link. But I think the
native gcc calls the wrapped ld and as, so let's do the same cross
compiling.
- Removed the binutilsCross from the glibc expressions. Now they are built
using the gcc-cross-wrapper, and they were built with the direct gcc and
binutils before this change.
- I think patchelf and strip don't break the cross-compiled binaries, so I
reallow them on cross compilation.
- I disable the checkPhase on cross compilation. This made gmp and libtool
fail when cross compiled, iirc.

libgmp comes with an extended config.guess script that features more
accurate CPU detection. Unfortunately, use of that script causes the
configure phase to choose fairly aggressive optimization flags and the
resulting binaries might not work on architectures other than the
machine those binaries were built on.
The standard GNU config.guess script, however, recognizes a CPU type of
'x86' only. Thus, libgmp chooses the following settings:
ABI="32"
CC="gcc"
CFLAGS="-m32 -O2 -pedantic -fomit-frame-pointer -mtune=pentiumpro -march=pentiumpro"
CPPFLAGS=""
MPN_PATH=" x86/p6 x86 generic"
