Subject: gtkdocize.in: ensure that m4 directory exists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some packages set AC_CONFIG_MACRO_DIR without shipping macros. These end up in errors
like

| ln: target 'm4/' is not a directory: No such file or directory
| cp: cannot create regular file 'm4/': Not a directory

Note: This error does not occure e.g when libtoolize is run before because it
creates macro directory.
