To avoid variable leakage from one step to another, isolate the
steps from each others by running them in their own sub-shell.
This avoids variables leaking from one step to the others.

Allow the user to configure extra flags to pass to the host compiler
at build time. Applies to both C and C++.
Useful on Ubuntu to turn off the stack protector and fortify defaults
so the program stands a better chance of running on other distros.

The GOLD linker is written in C++. Pass CT_CFLAGS_FOR_HOST as
CXXFLAGS to configure so that any host specific flags are passed
through.
It feels a bit funny passing CFLAGS as CXXFLAGS, but the PPL and GCC
target rules already do the same.

binutils 2.21 doesn't recognise the Cortex-M3 SVC instruction when
assembling with -mcpu=all. This was fixed by the 2.21.53 snapshot and

When CT_PARALLEL_JOBS is -1, set the number of parallel jobs to the
number of online CPUs + 1. Update documentation to match.
I find this useful when building in the cloud. You can use the same
.config file and have the build adapt to the number of processors
available. Limited testing shows that NCPUS+1 is faster than NCPUS+0
or NCPUS+2.

Add 'build', 'build-*', and 'install' as phony targets to the top level
Makefile.
I tend to do everything in tree with the build in a directory called
'build'. This interfered with the target 'build', making it think the
target was up to date, and stopping scripts/crosstool-NG.sh from being
regenerated.
Added 'install' as I often set the prefix to $PWD/install.

Even if the current process is highly parallel, crosstool-NG spends most
of its time in single-job steps on fast machines (with a 12-CPU system,
I approximate the parallel vs. non-parallel time to be in the order os
1 to 3; that is crostool-NG spends two-thirds of its time running
non-parallel jobs).
Some steps to build gcc can be paralleled, gaining a litle bit of time
on the whole compilation.

Building uClibc with libubacktrace requires libgcc_eh.a to be available,
but gcc does not build it unless it is configured to generate shared libs.
However, libgcc_eh.a does not *require* shared libs support, as it is a
static library.

uClibc-0.9.32 requires libgcc_eh.a (for ARM EABI), but only when libubacktrace
is enabled. As this is not the default, provide a workaround to disable linking
with libgcc_eh.a if libubacktrace is not selected.
This will however still break if uClibc is configured to enable libubacktrace,
but it requires a fix in gcc, and we can take care of that later.

The sysroot prefix dir was broken in #4960f5d9f829 due to a mishap
when making the out-of-sysroot lib/ symlink: the './' was mistakenly
changed into a single '.' .
Although Jonathan suggested restoring the missing '/' to restore it to
normal operation, I prefered using an explicit pushd/popd to be extra
sure of the symlink location and target, along with a fix in the sysroot
relative directory calculation.

Some packages are available as LZMA tarballs. LZMA is a relatively recent
compression algorithm; it's slightly better than bzip2, but offers much
faster decompression. LZMA is now deprecated in favor of XZ, but some
packages switched to LZMA when XZ was not yet available, or still in its
infancy. Latest XZ (which totaly obsoletes LZMA) offers a backward LZMA-
compatible utility, so we can check for 'lzma' nonetheless.
