A reasonable thing to do would be to download the autoconf, automake, 
and libtool tarballs from https://ftp.gnu.org/gnu/.  Build and install 
each one using the same installation prefix.  It is best if the 
installation prefix does not interfere with your operating system (the 
default of "/usr/local" normally works).

Relevant m4 files would appear in something like 
/usr/local/share/aclocal.  It is possible that you might want to 
install some other autotools-related packages.  If it is just some m4 
files that you need, it may be sufficient to copy the needed file from 
your operating systems /usr/share/aclocal directory.

Make sure that the bin directory for those tools is in your PATH 
before the OS-provided tools so the new software appears by default. 
Then do 'autoreconf --force' in your project directory to regenerate 
all of the autotool stuff.

Maybe this will make a difference.
