Even though HOSTOBJS are not referenced directly in subdirectory Makefile
snippets right now, robustness requires resetting the variable contents.

Many compilers need special flags to compile *.h files as regular
source code, if they will do so at all. Rather than hoping all
compilers will have such a flag and adding mappings for it, create
wrapper .c files for test building single headers.
This allows using the regular rule for compiling C files without the
need for special flags, and it also provides proper dependency tracking
for these objects.

nasm requires a trailing / on paths specified with -I.
It does no harm with yasm.

This simplifies adding extra flags for individual programs
and also allows more than one object file per program.

This allows non-standard replacements for the -c compiler flag.
Some compilers use other flags or no flag at all in place of
the usual one.

This adds a full identification probe of CC, AS, LD and HOSTCC,
and sets up correct flags and dependency tracking for each.

The flag was added to avoid excessive warning spam, but nowadays those
warnings no longer occur in such large numbers as to require silencing.
Besides, gcc-specific flags do not belong in the Makefiles.

This is a new library for audio sample format, channel layout, and sample rate
conversion.

This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

This library does not fit into Libav as a whole and its code is just a
maintenance burden. Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

FFT code only appears in libavcodec, so there is no need to reset the variable
when the build templates are instantiated for other libraries.

It will be further developed with a few incompatible changes.
ffmpeg.c will stay as is for some time, so any scripts using it won't be
broken.

This ensures the linker picks the just built libraries even
if LDFLAGS for some reason contains -L flags pointing at
other directories containing libav libraries.

The libs are added to the all target elsewhere, no need to do it
again here.

This variable is set to the same value for all directories.
Adding the -L flags directly to LDFLAGS is simpler and achieves
the same thing.

Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

The targets are now part of FATE and can be run as individual FATE targets.

GNU make 3.81 apparently does not support order-only prerequisites
with pattern rules, and thus fails to create the tools directory
if it is missing. Naming the objects explicitly in the rule makes
it work properly.

These commands have the same form, and using a common macro allows
it to be used elsewhere without further duplication.

Setting SRC_PATH to "." when building in-tree removes the need
for a quoted version of the source path since out-of-tree builds
are not possible if the pathname contains spaces.
