Like rev 2002, eglibc installs some bash scripts, but use the path to the
buildtool bash as the interpreter (on the shebang line). This is only a
symlink to the real bash, and thus is not available at runtime.
Fix that by assuming that shell on the target *will* be /bin/bash.

Since Subversion 1.6.13 was released, it is no longer possible
to checkout/export to the current working directory using '.'
(eg. "svn co bla://blabla/foo/bar ." no longer extracts the content
of bar into ./ but into ./bar).
Fix this by luring Subversion to extract into "$(pwd)", which has
the advantage of working both with all known versions so far.
At the same time, remove the useless redirection.
Adds support to enable/disable IOs of floating point values
(float, double, and long double).

I ran into some minor difficulties looking through the build log for a
particular file: I wasn't interested in seeing it unpacked, but only
when it is built or installed. Adding these two levels allows me to
differentiate between those cases.
[Yann E. MORIN: Those are blind log levels, and are used only to search
in the build-log afterward.]

Use the MIPS ABI selection to properly munge the uClibc config file.
This has the side effect to force the ISA:
- n32 ABI -> MIPS-III ISA
- n64 ABI -> MIPS64 ISA

When targeting mingw32, gcc expects to find its include files
in "mingw/include" instead of the traditional "usr/include".
[Yann E. MORIN: split the original patch]
Some time, someone updated the locale Makefile to use
newer pre-generated locales data, but did not upload
those.
So we just force using the existing, ageing archive,
dating back 20030818. Sigh...
It seems that using pre-generated locale data can be more problematic
than usefull in some circumstances.
Offer a config knob to enable/disable use of the pregen locale data.
Also, do not extract pregen locales data ourselves, it's broken.
I was unable to make the cross-ldd from uClibc to work, and
it is not possible to build it on non-POSIX system.
Besides, we have a generic script that is in the starting-blocks
to replace it, that will work for any C library, and also will
work on non-POSIX systems. Bonus!
Add several development libraries to the build of the mingw cross-compiler
to be used on target
Libraries:
PDCurses (port of the ncurses library)
GnuRX (the regex library)
DirectX
OpenGL

Add the option to build a cross-compiler for kernel type 'mingw'.
The resulting cross-compiler can be used to build applications on a Linux host
that can be run on a Windows target.
Compiler is build using the mingwrt and w32-api packages aviable from the
MinGW project (http://sourceforge.net/projects/mingw).
The windows headers (w32-api package) are extracting with the kernel_headers
step The libraries and other headers from both packages are build and
installed in the various steps of libc

glibc installs some bash-scripts, but uses the path to the buildtool
bash as interpreter (on the shebang line). This is only a symlink to
the real bash, and thus is not available at runtime.
Fix that by assuming that bash on the target *will* be /bin/bash.
A few facts:
- building the C library requires a proper core compiler
- core compiler is issued from one of the core passes
- the C library is required to build libstdc++
- newlib is only built for baremetal
- in bare metal, the final compiler is issued from one of the core passes
So we need to build the C library between core pass 1 and core pass 2.
The only place is eithe libc_headers() or libc_start_files(). The most
pertinent seems to be libc_start_files().
So we build newlib from libc_start_files(), and leave libc() empty.
For uClibc, the name of the Blackfin architecture is 'bfin'. Actually,
the naming of the architecture is quite messy: for toolchain tuples
and uClibc, it's bfin, but for the kernel, it's blackfin. We've
arbitraly choosen to name it "blackfin" in Crosstool-NG.
Add Blackfin-related uClibc patch to fix a build failure related to
fork() being used in unistd/daemon.c.
Yann E. MORIN:
Apply the patch to the kernel/linux build script to use 'linux'
in the noMMU tuples. See:
http://sourceware.org/ml/crossgcc/2010-04/msg00010.html
We can not rely on the user-provided version string (be it via the
choice, or manually entered), so fallback to reading version.h,
which is both reliable and always present.
It's now been a while that glibc switched to git from cvs.
Get rid of cvs to download glibc; this will make for a good
cleanup before we add git support! :-)
If the selected ARCH is dual-bitness (eg. supports 32- and 64-bit),
then we need to know the correct place where to fetch some headers.
Currently, this applies only to x86 variants: i386 and x86_64.
Using this: tar cf - -C "/some/place" |tar xf - -C "/some/other/place"
to copy a directory to another place does not properly fail (when it does).
Using this instead: cp -av "/some/place" "/some/other/place"
makes it easy to see why and how it failed.
Impacted:
libc/uClibc
debug/ltrace
tools/sstrip
scripts/populate
The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.
newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run
