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>

Say 'y' if you want to generate the toolchain with crosstool-NG
