Lucas De Marchi 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.

Lucas De Marchi 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.

Lucas De Marchi 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>
		])], ...)
