Fabrice Fontaine 1e0ee35a9d package/bird: fix build with autoconf >= 2.70 
Fix the following build failure raised since bump of autoconf to version
2.71 in commit ecd54b65c1:

checking for glob.h... no
configure: error: glob.h not found.

This is the same problem that we tried to fix in
03c148c8de by adding AUTORECONF = YES.

The analysis made back then is probably not entirely correct - the issue
only seems to occur with GCC8, not with any earlier or later version,
which hints at a compiler bug. Since the error involves some
LTO-generated functions, the trigger is probably the -flto=4.

Whatever the exact issue is, it is avoided if we make sure that our
CFLAGS replace the default ones instead of being added to them.
Currently, they are added because the configure script doesn't properly
detect that CFLAGS was set.

Add a patch (sent upstream months ago, but it didn't appear in the
release that has been done since then) that makes sure CFLAGS is
properly detected.

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 OFTC IRC.
