always include new global symbols

In the case that a new global symbol is defined in a file but not used
by a changed function, the symbol will currently not be included.

However, since it is global, another file in the patch my reference it,
but it will not be there.

This commit includes new global symbols so that they may be referenced
by changes in other files within the same patch.
