None of them are specific to the YASM assembler.

Fixes ticket #5546.

Also drop stray duplicate OBJCC config.mak entry.

This fixes several warnings of the sort
warning: label alone on a line without a colon might be in error

Previously, all link-time dependencies were added for all libraries,
resulting in bogus link-time dependencies since not all dependencies
are shared across libraries. Also, in some cases like libavutil, not
all dependencies were taken into account, resulting in some cases of
underlinking.

To address all this mess a machinery is added for tracking which
dependency belongs to which library component and then leveraged
to determine correct dependencies for all individual libraries.

Leaving those variables in an undefined state allows them getting implicitly
enabled when they are declared as weak dependencies of other components.
In that case, the library check is not run and required linker flags are not
added, resulting in a failing build.

Fixes linking when enabling libfreetype without libfontconfig.

The codec used in those files is WMV3/WMV9, not WMV2/WMV8.

The map is a sparse array and does not need a empty element to terminate
it.

The empty element is stored after the last one inserted in the list,
overwriting whichever element was next with zeros.
