Yes; the corresponding fix went in in 1.9a and is in 1.10:
<http://git.savannah.gnu.org/cgit/automake.git/commit/?id=b9df3285f2c32960ebeb979bbc6d76ea3e438ba4>

I suppose you can work around this bug by changing your code to this:

m4_ifdef([AC_PROG_OBJC],
   [AC_PROG_OBJC
    _AM_DEPENDENCIES(OBJC)],
   [AC_CHECK_TOOL([OBJC], [gcc])
    AC_SUBST([OBJC])
    AC_SUBST([OBJCFLAGS])
   ])

The m4_ifdef is presumably to cater to Autoconf versions before 2.60
which did not have an AC_PROG_OBJC macro.

But really, you should upgrade to Automake 1.10.2.

Cheers,
Ralf
