If links don't work, fall back to using the full source path as was
previously done.
This should fix build failures with MSVC.

Previously the full source path was embedded inconsistently in the debug
information between in-tree/out-of-tree builds.
The 'vpath %.inc' becomes necessary for finding
libavfilter/all_channel_layouts.inc in out-of-tree builds.
The full source path is still embedded in the debug information, but
it's now independent of whether building in-tree or out-of-tree.
The biggest improvement of this patch is that gdb now always searches
for the path relative to the source directory. It still also searches
for the full path.
Previously it searched only for the full path in out-of-tree builds,
making the debug information generated by Debian's buildds rather hard
to use.

This allows the user to override the directory for the installation
of the pkg-config files (from the default LIBDIR/pkgconfig).
It follows the usual behaviour of Makefiles generated by automake.

The macro hell sometimes make it difficult to trace the source of
an error, so it is easier to analyze the preprocessed output.
This patch makes this automatical by specifying DBG=1 on the
command line: a file ffmpeg/dir/file.asm gets preprocessed to
builddir/dir/file.dbg.asm, which is then compiled.

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

This more closely matches the actual use, also we use plain
strip without these flags for striping
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
This will check if -wN '..@*' is available and fall back on -x if not;
when none are available, do not run strip at all to prevent removing
functions that might be actually needed.
$(STRIP) always expands to something, because it is one of the commands
in the BRIEF list. This renders the condition pointless.

The implementation of 25cb0c1a involves lots of spurious labels.
The effect of keeping those labels around is making debugging harder.
Those labels are meaningless, and complicate the disassembly. Also,
gdb can't tell the difference between them and function entry points.
This new strip command is irrelevant to any usage of Libav that would
have used the old fully stripped version, because the old one was for
non-debug use.

This makes sure proper linker arguments are used for the tools and

linked using the usual -l flag while for test programs the full
name of the static library is used.
Signed-off-by: Mans Rullgard <mans@mansr.com>
The test programs use internal symbols so cannot be linked against the
shared libs. Linking against both shared and static is pointless and
might do something strange depending on the linker. This changes the
dependencies so the test programs are linked only against the static
library for the component they belong to.
