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.

toolchain: add a hidden config option to enable the toolchain package The usual way to enable a package using the package infrastructure is to use a config option so instead to add the toolchain package to the TARGETS variable in the Makefile add a config option like all the other toolchain packages.

toolchain: introduce a toolchain knob for NPTL As our architecture support expands to a number of architectures that do not implement NPTL threading, and the number of packages that depend on NPTL specific features, it has become necessary to be able to know whether the toolchain has NPTL support or not. This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in option that allows packages to know whether NPTL is available or not. This hidden option is: * Automatically enabled when glibc/eglibc or musl toolchains are used, either internal or external. * Automatically enabled when an internal uClibc toolchain with NPTL support is configured. It is left disabled otherwise for internal uClibc toolchains. * Configured according to a visible Config.in option for custom external uClibc toolchains.

toolchain-external: add support for musl C library This commit adds support for external toolchains based on the musl C library, as available from http://www.musl-libc.org. Note that the pre-built musl toolchains available from http://musl.codu.org/ are not working for the moment, since they lack sysroot support. However, this problem has been reported to the maintainer, who has already added sysroot support in his scripts at https://bitbucket.org/GregorR/musl-cross, and therefore the next version of the pre-built toolchains should work with Buildroot out-of-the-box. In the mean time, the musl-cross script must be used to build the toolchain.

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: 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).
