toolchain/crosstool-NG: use the package infrastructure
Move crosstool-NG to package/ and make it an autotarget package. This requires a new patch (now upstream). Now, the crosstool-NG toolchain backend only contains enough to build the toolchain, there's no more reference to building crosstool-NG as a package. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

-scripts, cc/gcc: do not fail on existing symlinks or build.log
-
-If the user builds a toolchain over an existing one, so, without removing
-CT_PREFIX_DIR, the build fails as the symlinks already exist, as does the
-build.log.
-
-This can also happen (for build.log) if the user first ran in download-
-or extract-only.
-
-Patch (with no SoB) originally from:
- Phil Wilshire <phil.wilshire@overturenetworks.com>
-
-Modified by me as it did not apply cleanly.
