0943f4b7b2 build-sys: fix conftest.c to work on arm
All tests for compiler support were failing with:

/usr/bin/ld: /tmp/ccwnVc2A.o: relocation R_ARM_MOVW_ABS_NC against `a' can not be used when making a shared object; recompile with -fPIC

7f8aa67131 core: remove tcpwrap support
tcpwrap is legacy code, that is barely maintained upstream. It's APIs
are awful, and the feature set it exposes (such as DNS and IDENT
access control) questionnable. We should not support this natively in
systemd.

Hence, let's remove the code. If people want to continue making use of
this, they can do so by plugging in "tcpd" for the processes they start.
With that scheme things are as well or badly supported as they were from
traditional inetd, hence no functionality is really lost.

d8c8508bad build: check for build/link flags harder
Use AC_LINK_IFELSE instead of AC_COMPILE_IFELSE to test for flags that
might succeed during compilation but not during linking. An example is gcc
compiled with libssp support but gnu-ld without it. In this case
-fstack-protector works fine during compilation but fails during linking
as several internal helpers are missing.

e9c1ea9de8 replace tabs with spaces in various files
The affected files in this patch had inconsistent use of tabs vs. spaces
for indentation, and this patch eliminates the stray tabs.

Also, the opening brace of sigchld_hdl() in activate.c was moved so the
opening braces are consistent throughout the file.

cdefbd6aeb build-sys: Append -Werror when testing flags
Clang don't treat unknown warnings flags as an error, but rather as a
warning. The result is that the detection for whic CFLAGS are supported
by this compiler will not work, since the compilation will succeed.

With this patch we now successfully detect clang doesn't support
-Wlogical-op, as opposed to previous behavior:

	checking if clang supports flag -Wlogical-op in envvar CFLAGS... no

We use this macro only for LDFLAGS and CFLAGS, so it's safe to stash
-Werror there.

eb2e280f9c build-sys: do not set CFLAGS directly
Set a separate variable for adding warning flags. Build systems are not
supposed to change CFLAGS and LDFLAGS, these are user variables.

c18514440d build-sys: fix AC_COMPILE_IFELSE tests
This removes some warnings when bootstrapping. The warnings were introduced
in autoconf 2.68. Reference:

http://www.flameeyes.eu/autotools-mythbuster/forwardporting/autoconf.html

The following code

	AC_COMPILE_IFELSE([
		<MY C CODE HERE>
		], ...)

is changed to

	AC_COMPILE_IFELSE(
		[AC_COMPILE_IFELSE([AC_LANG_SOURCE([
		<MY C CODE HERE>
		])], ...)
