Accept a local tarball name as the source of the Linux kernel headers,
rather than forcing the user to use either an upstream tarball, or a
local pre-installed headers tree.
Some components have configuration options that can depend on
generic options, so they should go below those.
uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls
So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.
This patch adds support for installing the gcc test suite. A helper
Makefile is provided for building and running the gcc tests.
The default configuration runs all gcc tests and requires automatic
ssh/scp login access to a networked target board. See README for
more details.
Note: Current feature is tested with the powerpc-unknown-linux-gnu
sample but it should work with others as well.

Insight seems to be very slow to follow up on mainstreram gdb.
Latest snapshots are more than 6 months old.
Moreover, I don't have time to maintain insight support in crosstool-NG;
and, because I don't use it, I am unable to find any breakage.
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:

When building a baremetal cross compiler I want to be able to select
the elf format and not be forced to build the elf2flt package.

If threads are disabled in libc, we don't want to enable them in the
final compiler. Doing so pass the configure stage, but fails latter on
a missing <pthread.h>.
Moreover, we don't want to build libgomp if threads are disabled; its
configure script would fails anyway.

Hide the prompts for some behavioral options, for which the upper-layer build
system is responsible for:
- parallel jobs and maximum load
- use pipes
- use custom shell
When crosstool-NG is used as a backend, it is the responsibility of the
upper-layer build-system to properly set paths, so we just hide the
prompts in this case.
sstrip is now alone in its 'tools' menu, and we will probably never gain
any other 'tool'. Besides, sstrip is just strip, but a little bit more
agressive, so it deserves going to the 'binary utilities' menu.
When acting as a backend for a build-system, we should not build
any application that runs on the target, that is:
- no native gdb
- no companion libraries
- no binutils libraries
- no debug tools (save for gdbserver)
- ...
Here, we simply prepare the (hidden) config option that will detect
that we are acting as a back-end.
Update doc accordingly.
The companion libraries on the target are required only for internal use by
binutils and gdb. The user should not have to know about this, so hide the
option.
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! :-)
It's broken anyway. Eg.:
- user is already niced at 10
- user configures to renice at 5
- breaks because user is not allowed to 'boost' his/her nice value
Bette let the user handle the renice with:
nice -XX ct-ng 'action'

Even if the selected ARCH does not support different bitness (or we do
not support building with another bitness), still select the appropriate
bitness.
