compiling bison-3.0 on AIX 5.3

[Michael Felt]

The make (also using gmake) command for bison 2.7.1 works fine, however the
same configure statement, followed by make gives the following error:

make -d outout: tail

Suff_FindDeps (./examples/extexi)
        No known suffix on ./examples/extexi. Using .NULL suffix.

Willing to test, but I have no clue where this is coming from, nor why.
