Jörg Krause 9c7182f30c package/cc-tool: fix gcc 5 issue
The version of boost.m4 initially included in cc-tool has an issue
with gcc5 (one of its tests fails due to the first change described in [1]
"Preprocessor issues").

This was fixed upstream (boost.m4 project) in Nov 2014 [2].

We add the latest commit [3] of upstream boost.m4 plus a patch from github PR
[4] to add detection for gcc 5.1.

Fixes:

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.
