+Use wget instead of curl
+
+While crosstool-NG did support either curl or wget in the past, it now
+only supports curl. Unfortunately, Buildroot uses wget for all its
+downloads, so wget is a hard dependency of Buildroot, while curl
+isn't.
+
+Instead of adding curl as a new Buildroot dependency, or building curl
+for the host, we simply tweak crosstool-NG to use wget instead of
+curl.
+
+The script/functions change has been provided by Yann E. Morin.
