Stefano Sabatini 5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.
