Thomas Petazzoni 136c8862cf package/dhcpdump: fix build at -O2 
Since commit aa556e2035
("utils/genrandconfig: test with BR2_OPTIMIZE_2=y"), we are doing
builds at -O2 instead of -Os. This has unveiled an issue in the
strsep.c file:

strsep.c:65:23: error: register name not specified for 'delim'
  register const char *delim;

This strsep.c compatibility code is compiled in if HAVE_STRSEP is not
defined, but dhcpdump does not use any kind of configure script to
detect the availability of strsep(). Therefore by default, it gets
compiled in, and the "register" specifier used for some variable
declarations in strsep.c cause build issues at -O2.

A previous commit in Buildroot from
c2a7f0d605 ("dhcpdump: Fix strsep()
feature test"), attempted to fix this problem by changing the test on
HAVE_STRSEP by a test on _BSD_SOURCE.

Unfortunately, _BSD_SOURCE is not meant to be tested: it's a feature
macro that is meant to be *defined* by some code to tell the C library
headers to expose (or not) some given functionality.

So instead, we basically revert commit
c2a7f0d605 by dropping the patch, and
pass -DHAVE_STRSEP in the CFLAGS when building dhcpdump.

README

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 Freenode IRC.
