When compiling glibc 2.16 and gcc 4.7.4 with CT_ARCH_FLOAT="hard",
I end up in a dynamic linker called /lib/ld-linux-armhf.so.3, but
gcc compiles the binaries with an ELF interpreter /lib/ld-linux.so.3.
That doesn't work.
This patch (which is included in recent gcc version and also is included
in Linaro 4.7 versions) fixes the problem. I just stripped the ChangeLog
diff from the original commit.

We had following problem: We're building a toolchain with an old glibc
version for compatibility with old Linux distributions (glibc 2.9). This
version requires make < 4 to build. However, the configure script of
glibc looks for make in the order "gnumake", "gmake" and "make". So when
"gmake" is available in the system (which is the case on Gentoo Linux
per default, unfortunately), then configure finds the system gmake 4.1
instead of the ct-ng make 3.82.
This patch adds an option to install a symlink so that 'gmake' is also
available in the old version when building toolchains.

Canadian Cross compile for baremetal fails with error;
checking for the value of EOF... configure: error: computing EOF failed
which is due to libstdc++ configure not being able to find stdio.h
Having all modes of the core compiler copyheaders from CT_HEADERS_DIR
(in combination with previous patch for newlib to add a do_libc_start_files
function to copy into the CT_HEADERS_DIR) resolves this.

Currently, the obsolete RPC headers are only installed for eglibc,
but glibc has the same /deficiency/, so install the obsolete RPC
for both.

Can safely skip the core pass-1 for normal baremetal builds,
but when building a canadian baremetal, the repair_cc
functionality (GCC_FOR_TARGET) in gcc.sh will force the
core pass-2 to attempt to build gcc and libgcc without a
${CT_TARGET}-gcc existing, causing a failure on
${CT_TARGET}-gcc -dumpspecs > tmp-specs

The current .gitignore files cause changes to files which are actually part of
the repository to be ignored. This commit modifies the rules so that this does
not happen. The files that were affected are:
config/global/paths.in
contrib/gcc-test-suite/Makefile
docs/ct-ng.1.in
kconfig/Makefile
(as revealed by 'git ls-files --ignored --exclude-standard')

As per the glibc release notes for 2.20:
--------------------------------------------------------------------------------
All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).
--------------------------------------------------------------------------------
There isn't a ports directory anymore. So disable using and forcing it.

Yes, I missed the backslash which messed up the linaro stuff.
The more I look at this code, I feel it needs to be refactored a bit. So
I'll come back to this in the future and clean it up.

It's not my day.
linaro_version is a filter. If it is not a linaro toolchain, it will
just be CT_{CC,GDB}_VERSION. If it is a linaro toolchain, CT_{CC,GDB}_VERSION
will be prefixed with 'linaro-' and will not match linaro_version, as
linaro_version will just have the part after 'linaro-'.
This *really* fixes the issue :sigh:
Thanks again to @elsonwei for being right the first time!

I messed up the previous commit.
I only updated half the config file, and the latest 4.8 is 2014.08.

linaro_version and linaro_series are defined but not set if we are not
configured for linaro builds.
Therefore we need to default them to "" (null string).

No longer recommended practice to use --enable-add-ons=nptl, so
for 2.20 and later (along with custom glibc), don't add the
CT_THREADS to the addons_list

This change updates the download locations to default to the official
download site.
For gcc and gdb, also separate out the linaro download locations so that
if you are downloading the linaro variant, it skips trying to download
from the official gcc mirror.

Without this fix, elf2flt will blow up complaining that it can't resolve
dlopen() and friends. One has to explicitly pass '-ldl' on the final
linking command line, because the system linker is not resolving
indirect dependent shared libraries.
I've needed to this patch for several years on Fedora systems.

When try to build the static toolchain, binutils failed.
I have checked the libtool script, and found that the following option
-all-static
-static
-static-libtool-libs
are processed in a strange way. If any one of those three options
appears firstly in the cmdline, all others will be neglected. Our
LDFLAGS is ".... -static -all-static -o", so the -static option
takes the real effect, and the -all-static has no useage actually!
that is the cause of the failure.

BSD grep does not interpret a null alteration. It complains about an
empty sub-expression, e.g.:
$ grep --version && grep -E '^(# |)CT_' .config
grep (BSD grep) 2.5.1-FreeBSD
grep: empty (sub)expression
This patch replaces the null alteration with a zero or once quantifier
which works with both BSD & GNU grep.
$ grep --version && grep -E '^(# )?CT_' .config
grep (BSD grep) 2.5.1-FreeBSD
