Some compilers choke on -Wall, so only add the flag after checking it works.

Older nasm versions have trouble assembling certain AVX instructions, but the
current AVX check did not detect this. Update the check to use an instruction
that triggers the nasm problem.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

046f081b reorganized the CPPFLAGS to no
longer add -D_POSIX_C_SOURCE unconditionally, but only on systems (e.g.,
glibc based ones) that require it.  As kFreeBSD uses glibc, it needs to
be treated similar.

Additionally, _BSD_SOURCE is turned on to enable some additional types
such as caddr_t, which are normally enabled on BSD but not with glibc.

SIGINT for quitting should be enough for everybody.

Enabling libpostproc automatically should give it more compile coverage
and save the FATE box maintainers some configuration hassles.

Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems
since it causes certain system functions to be hidden on some (BSD) systems.
The solution is to only add the flag on systems that really require it, i.e.
glibc-based ones.

This change makes BSD systems compile out-of-the-box without the need for
adding specific flags manually.  It also allows dropping a number of flags
set manually on a file-per-file basis, but were only present to work around
breakage introduced by the presence of _POSIX_C_SOURCE.

Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems.  We use XSI extensions
in several places already, so it is preferable to define it globally instead
of littering source files with individual #defines only needed for glibc.

The low quality mode is off by default and never tested.  The high
quality mode is also plenty fast enough.

It was used for an old implementation of the SBR filterbank.

./configure --disable-everything --disable-ffplay --enable-decoder=aac works.

This fixes compilation on DOS.

This restores the behaviour of running only the builtin
regression tests when no path to external samples is given.
aa3805a4 inadvertently broke this by always setting SAMPLES
to something.  Using := makes the ifdef test work as expected
when the FATE_SAMPLES environment variable is empty.

Stripping is generally best left to package management tools, and
since unstripped copies are kept in the build tree, any arguments
about saving space (no matter how insignificant) are void.

The normal dependency tracking system disables them just fine.

It is automatically disabled on both mingw and dos due to
the lack of fork.

ICC lies about the version of gcc it emulates, which results
in unsupported attributes sometimes being used.  The warning
is an annoyance and should be disabled.
