Subject: [PATCH] Fix autoreconf error due to m4 CRLF issue (#1717)

Trying to run `autoreconf -fiv` on a Windows system using wsl causes the following error:
```
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --copy --force
libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'build-aux'.
libtoolize: copying file 'build-aux/ltmain.sh'
.ibtoolize:   error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL_AMFLAGS=-I m4
autoreconf: libtoolize failed with exit status: 1
```
This is likely due to a CRLF error in the makefile. This commit applies the following fix:
