Once you have executed the top-level autogen.sh, which contains the lines

for file in codeset.m4 fcntl-o.m4 glibc21.m4 relocatable-lib.m4 visibility.m4; 
do
  cp -p srcm4/$file libcharset/m4/$file || exit $?
done

the same *.m4 files will be present also in libcharset/m4/.

The autogen.sh distinguishes these cases:

# Usage from a git checkout:                 ./autogen.sh
# This uses an up-to-date gnulib checkout.
#
# Usage from a released tarball:             ./autogen.sh --skip-gnulib
# This does not use a gnulib checkout.

Maybe you used a git checkout but passed the option --skip-gnulib? That
won't work.
