It will be used in other places than lavc.

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this
integration was heavily inspired from the blog entry by Mike Melanson:

This fixes removal of TOOLS as well as HOSTPROGS declared in the
top-level Makefile.  The clean target in common.mak needs to be
eval'd since the variables used within are reset for each library.

This is consistent with usual ARM nomenclature as well as with the
VFPV3 and NEON symbols which both lack the ARM prefix.

This is useful for debugging.  Dependencies for these files are not
generated due to limitations in many compilers.

This is more consistent with the way we handle C #includes and
it simplifies the build system.

This makes sure the previously always installed public header
lzo.h is installed if the LZO functionality is enabled.

This allows targets to include special objects when linking
executables without including them in (shared) libraries.

This avoids repeating cmdutils.o in both the prerequisites and
the link command.

The code fails to compile and is broken beyond repair.

This enables replacing the -l and -L flags used to specify the
just-built libraries when linking the tools and shared libs with
non-standard syntaxes.  System library flags are already handled
by the filtering mechanism in configure.

This adds new HOSTLD and related settings for host linker allowing
it to be different from HOSTCC.

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.

This simplifies adding extra flags for individual programs

the usual one.

This adds a full identification probe of CC, AS, LD and HOSTCC,

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

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.
