package/uboot-tools: bump to version 2015.04

Bump to version 2015.04:
  * Enable optional support for FIT Signature Verification
  * Remove patch 0002-nostrip, it's upstream
  * Add musl patch
  * Add hash file

This patch supersedes "package/uboot-tools: bump to version 2015.01"
http://patchwork.ozlabs.org/patch/440396/

[Thomas:
  - Rewrap Config.in help text.
  - Move the paragraph about potential license compatibility issue
    from Config.in.host to Config.in, since it's really on the target
    package that such issues can be a problem.
  - Use += instead of = when adding the dependency on openssl, so that
    if other dependencies get added later, we don't overwrite them
    mistakenly.]

-Subject: [PATCH] tools/env: change stripping strategy to allow no-stripping
-
-When building the U-Boot tools for non-ELF platforms (such as Blackfin
-FLAT), since commit 79fc0c5f498c3982aa4740c273ab1a9255063d9c
-("tools/env: cross-compile fw_printenv without setting HOSTCC"), the
-build fails because it tries to strip a FLAT binary, which does not
-make sense.
-
-This commit solves this by changing the stripping logic in
-tools/env/Makefile to be similar to the one in tools/Makefile. This
-logic continues to apply strip to the final binary, but does not abort
-the build if it fails, and does the stripping in place on the final
-binary. This allows the logic to work fine if stripping doesn't work,
-as it leaves the final binary untouched.

-Cc: Sonic Zhang <sonic.zhang@analog.com>
----
-An improved solution would be to be able to override STRIP completely
-by setting it to /bin/true, but the main Makefile enforces STRIP =
-$(CROSS_COMPILE)strip.
