Do not use -Wl,-no-undefined flag on OpenBSD 5.x (tested on 5.0)

this fixes a problem found by obnox where the -L path for CUPS was put
before the path to internal libraries. The install path for CUPS
happened to be the same as for a old system libtevent, which meant we
linked against the old tevent instead of the correct one from our
private library paths.
The problem was that we were adding the -L paths directly to the
ldflags. The waf core code (in ccroot.py) only adds more paths if they
are not there already. So by adding it in ldflags it was not added at
the end of the list. The fix is just to not do the -L processing in
wafsamba and let the waf core do it in the right order

The s3-waf build system is a key component of the top level build, but
with this commit is is no longer available directly. This reduces the
number of build system combinations in master as we prepare for the
Samba 4.0 release.

Normally under UNIX, uninitialized non-static global variables get
placed in the "common" section, where they are merged at link time.
This means if two C files define "int debug", they will end up
referring to the same variable. Or if one does "float level" and the
other does "int level" you'll get an accidental union.
Such bugs can be hard to track down; fortunately GCC offers
-fno-common to disable this feature. It didn't reveal any places
which need fixing, however).

In samba3 there are a lot of warnings generated that make it a bit hard to track
and monitor other build warnings.

this will be used by the s3 top level build to work out how to undo
the effects of -Wl,-no-undefined

We should avoid generating a backtrace in a normal
error case, just because sys.exit(1) isn't known.

On Solaris with sun studio compiling an executable with -liconv even if
there is no libiconv.so or libiconv.a will work but not for a shared
lib.
This problem leads to build problem as the linker won't be able to find
libiconv when building shared lib as liconv is wrongly specified

this makes it easier to add project rules that are only run in

moved it out of the general waf build as the s3 waf build cannot yet
handle linking with -Wl,-no-undefined

this flag was not being propogated to our link rules, so we were not
in fact enforcing no undefined symbols in libraries.
|
|
|
|
the linker supports such a flag.

this changes CHECK_BUNDLED_SYSTEM() to honor the checkfunctions and
headers options even for libraries found with pkgconfig.

Tridge, please check

There 2 reasons for this change:
- This is how autoconf tests work and it makes config.log much more useful
- The waf c preprocessor ignored changes in bin/default/__confdefs.h when using
waf configure -C, because is outside of the configure tests project path
and handled like a system header.
Many thanks to ita for pointing out the fix.

this also makes the output of define_ret configure tests show up
in the configure output

This allows you to easily cross-compile even without a --cross-execute
emulator

Building a RPM from the fedora spec file now works with minimal changes

this enables use of a cross-compilation emulator, so configure tests
run on an emulator of the target platform

A library may be initially set as empty if it wasn't needed for a list
of functions in CHECK_FUNCS_IN(). A later check may require the
library.

this gives appropriate colors on output, and ensures it works with
compiler output

Added configure options for --fatal-errors and --picky-developer. This

we don't want paths in config.h, as that just causes full rebuilds
when you change --prefix. Better to use cflags= on the right subsystem
|
|
This allows us to give a single 'Checking ...' msg for a compound
set of tests.

Based on a problem with res_ndestroy() on sunx in the build farm, I've
changed the default strategy for finding functions with
CHECK_FUNC(). It now accepts either a macro of a linked function, but
won't accept a declaration only unless you set link=False.

use python string conventions for function comments

distros can set --bundled-libraries=NONE to force use of all system
libraries. If the right version isn't found then configure will fail.
Users may choose which libraries to use from the system, and which to
use bundled libs. The default is to try system libs, and use them if
their version matches the one in the source tree.

This creates a full shared lib, and a binary that uses it. Then it
tests that the binary runs correctly, relying on rpath
Thanks to Thomas for the code for this!
