Integration with Buildroot Toolchain Eclipse plugin

The Eclipse plugin at
https://github.com/mbats/eclipse-buildroot-toolchain-plugin allows
users of Eclipse to easily use the toolchain available in
Buildroot. To do so, this plugin reads
~/.buildroot-eclipse.toolchains, which contains the list of Buildroot
toolchains available on the system, and then offer those toolchains to
compile Eclipse projects.

In order to interface with this plugin, this commit adds an option
that allows the user to tell whether (s)he wants the Buildroot project
toolchain to be visible under this Eclipse plugin. It simply adds a
line in this ~/.buildroot-eclipse.toolchains file.

Makefile: export a few variables to help support scripts

Support scripts (in support/) may need to parse the .config file, so give
them an easy access to it, by exporting BUILDROOT_CONFIG with the fully-
qualified path to .config.

Also, post-build scripts may need to reference a few locations, so export
those, too.

Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR
is used internally, while O is used on the command line, which makes it a
bit ambiguous to know which to use. As users use O= on the command line,
they will probably tend to use that in their post-build scripts.

Update doc accordingly.

SHA1 functions from OpenSSL is OpenSSL is already available, or the
SHA1 functions from libgcrypt is libgcrypt is already available, or if
neither OpenSSL nor libgcrypt are enabled in the configuration, we

elfutils: towards uClibc support: FTS functions

The fts_*() functions are optional in uClibc, and not compiled in our
default configuration. The best option would be to migrate this
elfutils code to the nftw family of functions, but it requires quite
some work.

So we have several options here:

 *) Enable fts_*() functions in our default uClibc configuration. Not
    nice since only one package needs them (the help text of uClibc
    for fts_*() functions explicitly mention that they have been added
    to be able to build elfutils).

 *) Use gnulib, but it is quite heavy to setup, requires modifications
    to configure.ac, and other things.

 *) Copy the fts function from uClibc into elfutils source code. This
    is the solution used below. uClibc is LGPL, and elfutils is
    LGPL/GPL, so there should not be any licensing issue.

Of course, the fts_*() functions are only built if they are not
already provided by the C library.

perf: add kernel version checks

perf without libelf can only be built since kernel 3.7, so error out

kernel without libelf.

Unfortunately, those tests can only be build-time checks as we either
need to know the real kernel version (i.e, using LINUX_VERSION would
not be correct as it can be a Git commit ID, or Git tag), or have
