[PATCH] Add EXEEXT to doc/local.mk

[Di-an JAN]

This fixed a build failure on Cygwin, where EXEEXT=.exe
...
Making all in .

rm -f doc/cross-options.texi doc/cross-options.texi.tmp
make  src/bison

Instead of the minimal change of adding $(EXEEXT), I made src/bison
a real prerequisite since it's in the same Makefile now.

Tested on Cygwin with `touch src/getargs.c; make' and spot checking
with info and pdf.

        Add $(EXEEXT) to src/bison used as a make prerequisite.
        * doc/local.mk (cross-options.texi): Use src/bison as prerequisite
        instead of src/getarg.c.  Don't make src/bison explicitly.
