Libtool seems to output text in US-convention:

...
libtoolize: putting auxiliary files in `.'.
libtoolize: copying file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in
and
...

SUGGESTION

For output display in international context the double quotes would work
better (backquotes are not used in Asia, Europe). The double quotes
would also be shell friendly in a way that the text is cut-n-paste
ready, whereas backquotes are a little problematic (a shell
metacharacter).

The following patch would be start to change the output to:

...
libtoolize: putting auxiliary files in ".".
libtoolize: copying file "./ltmain.sh"
libtoolize: Consider adding "AC_CONFIG_MACRO_DIR([m4])" to configure.in
and
...
