Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC} Currently, when we need to do a conditional on the type of C library used, we need to take into account the three toolchain backends. As we are going to add eglibc support to the Buildroot toolchain backend, it would become even uglier, so this patch introduces two new hidden options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that exist regardless of the toolchain backend. The entire Buildroot code base is converted to use those options. Note that we have intentionally created only one option (BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are essentially the same, as far as Buildroot is concerned.

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.

toolchain: make external toolchain the default for AArch64 Our internal toolchain backend does not yet have support for AArch64, and Crosstool-NG also does not have support for AArch64 at the moment (though it should be coming quickly since the Linaro AArch64 toolchain is generated with a modified Crosstool-NG version).

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>

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.

toolchain. Buildroot can either download automatically a
toolchain, or use an already installed toolchain.

bool "Crosstool-NG toolchain"
toolchain/crostool-NG: mark as deprecated For the following reasons: - it used to be broken without anyone noticing for a long time, - it is still not fully integrated within the Buildroot set of options, - it has not gained much traction (not even I use it), - I've always argued that sustained development should use an external toolchain, and not rely on building one with Buildroot, - I did not submit any of the enhancements requested during the last developpers' day in Brussels, - I have neither the incentive nor the time to maintain and enhance it, it is time to deprecate the crosstool-NG backend for the 2013.05 release. Then, it will be entirely removed early in the 2013.08 cycle, to let some time for those that rely on it to voice their opinions. ;-) Signed-off-by: "Yann E.

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).
