Hollis Blanchard 38de434123 download: fix file:// BR2_PRIMARY_SITE (download cache) 
wget is the only downloader currently usable with BR2_PRIMARY_SITE, and that
doesn't work at all for file:// URLs. The symptoms are these:

	support/download/dl-wrapper -c '2.4.47' -d '/PATH/build/sw/source/attr' -D '/PATH/build/sw/source' -f 'attr-2.4.47.src.tar.gz' -H 'package/attr//attr.hash' -n 'attr-2.4.47' -N 'attr' -o '/PATH/build/sw/source/attr/attr-2.4.47.src.tar.gz'  -u file\|urlencode+file:///NFS/buildroot_dl_cache/attr -u file\|urlencode+file:///NFS/buildroot_dl_cache -u http+http://download.savannah.gnu.org/releases/attr -u http\|urlencode+http://sources.buildroot.net/attr -u http\|urlencode+http://sources.buildroot.net  --
	file:///NFS/buildroot_dl_cache/attr/attr-2.4.47.src.tar.gz: Unsupported scheme `file'.
	ERROR: attr-2.4.47.src.tar.gz has wrong sha256 hash:
	ERROR: expected: 25772f653ac5b2e3ceeb89df50e4688891e21f723c460636548971652af0a859
	ERROR: got     : e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
	ERROR: Incomplete download, or man-in-the-middle (MITM) attack

In the case of custom Linux kernel versions, this is fatal, because there isn't
necessarily a hash file to indicate that wget's empty tarball is wrong.

This seems to have been broken by commit c8ef0c03b0, because:
1. BR2_PRIMARY_SITE always appends "urlencode" (package/pkg-download.mk)
2. Anything with the "|urlencode" suffix in $uri will end up using wget due to
   the backend case wildcarding.
3. The wget backend rejects file:/// URLs ("unsupported scheme"), and we end up
   with an empty .tar.gz file in the downloads directory.

Fix that by shell-extracting the backend name from the left of "|". I'm not
positive if all URLs will have a "|", so this code only looks for a "|" left of
the "+".

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
