Both gcc and clang generate warnings for unsupported -f$FLAG by
default, meaning that the previous implementation would consider
unsupported flags as supported (as a warning is not an error that
fails compilation).
The addition of -Werror treats warnings as errors, and will prevent
false-positives in terms of -f$FLAG support.

mingw (both 32 and 64) provides a number of functions that have no C
linkage, but are only available as static inline. Define a macro that can
check for the function declaration but acts like AC_REPLACE_FUNC.
Use the new macro for asprintf/vasprintf (previously implemented in
configure.ac directly).

GCC takes the last -O* option, which defaults to -O0 anyway. With
./configure forcing -O0, there was no way to select a custom
optimization level via external CFLAGS.
Optimizing VLC code for size is probably not such a great idea,
considering that media playback is performance critical. There are
better ways to reduce code size than -Os, e.g. Thumb(2) code on ARM.
And of course, removing unneeded plugins and feature is the best way
to reduce code size.
Loop during autoconf since we always use fixed strings for the first
parameter anyway. Probably saves some runtime too ;).
