build: drop the 'fixacocal' auxiliary script

build: drop the 'fixacocal' auxiliary script

The comments in that script state that its use is only required to
work around issues in aclocal from Automake 1.10, while the rest
of the Gettext build infrastructure assumes Automake >= 1.11 anyway.

* autogen.sh: Drop invocations of 'fixaclocal', simply invoke the
'aclocal' program directly.
* build-aux/fixaclocal: Remove.
* Makefile.am (EXTRA_DIST): Stop distributing it.
(ACLOCAL): Drop redefinition in function of 'fixaclocal'.
* gettext-runtime/Makefile.am (ACLOCAL): Likewise.
* gettext-runtime/libasprintf/Makefile.am (ACLOCAL): Likewise.
* gettext-tools/Makefile.am (ACLOCAL): Likewise.
	* gettext-tools/examples/Makefile.am (ACLOCAL): Likewise.
