SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

This fixes leftover issues from 14abeaa4 which caused make
rules for programs to not match up properly when the executable
suffix was nonempty.

This includes moving libavformat/output-example to doc/examples/output.

This will allow cleaner integration of building example programs.

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 is needed to link tools/cws2fws using a linker with non-standard

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.

nasm requires a trailing / on paths specified with -I.

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,

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.
