tools: bison: do not install or uninstall macros

There is a clobbering between bison and gnulib for installing
the macro file bison-i18n.m4 where gnulib has a newer version
while bison will replace it with an outdated version if built afterward.

Other builds depend on the changes made to the bison-i18n.m4 file and are
only included using aclocal unless other modifications are made in each case
in order to force imported macros from gnulib to override aclocal macros.

Gnulib is integrated within bison, however it is not with a bootstrap script
and there is already a reverse dependency between the two, where bison
is indirectly required for gnulib to start building. Therefore, do not allow
the building or cleaning of bison to install or uninstall m4 files.
