0.11.5: gettextize with external

[Akim Demaille]

Hi!

Running gettextize on a project that is not including intl/ still
copies and installs m4 files that are not needed.  In fact, the
following paragraph is not honored by gettextize:

`aclocal.m4' at top level
-------------------------

   If you do not have an `aclocal.m4' file in your distribution, the
simplest is to concatenate the files `codeset.m4', `gettext.m4',
`glibc21.m4', `iconv.m4', `intdiv0.m4', `inttypes.m4', `inttypes_h.m4',
`inttypes-pri.m4', `isc-posix.m4', `lcmessage.m4', `lib-ld.m4',
`lib-link.m4', `lib-prefix.m4', `progtest.m4', `stdint_h.m4',
`uintmax_t.m4', `ulonglong.m4' from GNU `gettext''s `m4/' directory
into a single file.  If you have suppressed the `intl/' directory, only
`gettext.m4', `iconv.m4', `lib-ld.m4', `lib-link.m4', `lib-prefix.m4',
`progtest.m4' need to be concatenated.



Thanks!
