toolchain/crosstool-ng: allow pre-downloading the sources
On "make source", just download the required sources, and do not build the entire toolchain. This requires a new patch against crosstool-NG (got from upstream). The "uclibc-source" rule requires an installed and configured crosstool-NG, so it has to be after the variables declaration. For consistency, move down the main rule "uclibc". 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.
