uClibc-ng does not support PIE for some architectures as
arc and m68k. It isn't implemented in the static linking case, too.
With musl toolchains you might have static PIE support with little
patching of gcc. Static linking for GNU libc isn't enabled in
buildroot. Fixup any package using special treatment of PIE.

Even though ARC gcc understands "-pie" option and attempts to generate
PIE binaries as of today PIE is not really supported for user-space
applications.
So we disable PIE detection if building for ARC.
That first fixes http://autobuild.buildroot.net/results/57a/57a6180809bc51f7206280533f0b9898ce4cfbb4
and also prevents execution of non-supported PIE binary in runtime.
Interesting enough reported build failure is not directly related to PIE
it looks like if PIE is enabled then successful detection of explicit_bzero()
happens erroneously.
A simple test app that mentions explicit_bzero() while built with
"-pie" gives this output:

For some reason, the hash file added in commit
ee6c9f5a1b by Gustavo turns out to be
wrong, so this commit replaces it with the proper hash, also added
after checking the GPG signature.
While at it, we switch to using a .bz2 tarball.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.
