support for AM_CPPFLAGS

[Claudio Fontana]

Hello,

while trying to improve current support in gnulib for internal gettext,
I produced this patch, which I use successfully in the packages I
maintain to support per-package additions to AM_CPPFLAGS.

The patch is a unified p1 diff.
I suggest this for inclusion in the gnulib CVS.
