Subject: [PATCH] * Make sure wget downloads are stored with filenames not
 containing any html garbage (& and = signs as a result of http_get
 parameters). * Have wget_unpacked return the actual path where the files were
 unpacked via the _EXTRACT_UDIR env variable. In most cases this is simply the
 path that was requested, but sometimes, a tarball or zip file adds its own
 relative path. The _EXTRACT_UDIR variable will take this into account by
 analysing the contents of the tarball/zip file.

These changes will be used in the revived cross-compile script.
