Add BR2_CROSS_TOOLCHAIN_TARGET_UTILS to allow bundling of some useful debug apps with a deployed cross toolchain. Should probably do ltrace as well... Also, add another compat symlink for cross gdb.

Select whether to use the toolchain provided by buildroot
or an external toolchain.
Some vendors provide toolchains in binary form, some in
source form.

bool "Buildroot toolchain"
toolchain: introduce BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS Unfortunately, the official Blackfin toolchains are built without the shadow password support, so our default Busybox configuration fails to build. Therefore, we introduce a new hidden knob BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS, which is set to yes for Buildroot internal toolchain, for toolchains generated by the Crosstool-NG backend, for Glibc external toolchains and for Uclibc custom external toolchains. It is left unset by the Blackfin toolchain profile. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOT Newer versions of GDB need pthread debugging support if threads are enabled, which is always the case for glibc but is a configure option for uClibc. We have solved this for internal toolchains by selecting the BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this option isn't available when ctng/external toolchains are used, mconf prints ugly warnings and the build may fail if an external uClibc toolchain without pthread debugging support is used. Fix it by introducing 2 more hidden config options: - BR2_TOOLCHAIN_HAS_THREADS_DEBUG - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED The first tells us if the toolchain HAS pthreads debugging support, and is checked by check_uclibc_feature in helper.mk for external uClibc based toolchains. The second tells us if the toolchain is ABLE TO provide pthreads debugging support if threads are enabled, either because it's an internal toolchain where we can force enable it or an external glibc/eglibc toolchain or uClibc with the option enabled. Crosstool-ng forcibly enables this support, so those will always work. The preconfigured uClibc-based toolchains we have also all enable it. Finally, show a comment if this isn't the case so the (external toolchain) user knows why. This is placed outside the choice option, as menuconfig has a bug where it doesn't show choice selections which only contain comments. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

bool "External toolchain"
toolchain: add support for external toolchain profiles and download Instead of letting the user define all the details of his external toolchain, we define a set of profiles for well-known external toolchains (CodeSourcery ones only at the moment, can easily be extended with other toolchains). Once a profile has been choosen, the user is offered the choice of either letting Buildroot download and install the external toolchain, or (as before) to tell Buildroot where the toolchain is installed on the system. We of course provide a "custom profile", through which the user can configure Buildroot to use a custom external toolchain for which no profile is available.

Select if you want to use an existing cross-compiling
toolchain. Buildroot can either download automatically a
toolchain, or use an already installed toolchain.

Say 'y' if you want to generate the toolchain with crosstool-NG
( http://ymorin.is-a-geek.org/projects/crosstool )
This is considered experimental, and you can expect some breakage.

toolchain: use same gdb Config.in for internal/external toolchains We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).
