commit: http://git.buildroot.net/buildroot/commit/?id=b9882925a438824b2e34b196cd7ef5382d1fb9cb
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
