* gnu/packages/emacs.scm (m17n-lib)
[source]: Add m17n-lib-1.8.0-use-pkg-config-for-freetype.patch.
[native-inputs]: When cross-compile add pkg-config, libtool, gettext-minimal,
autoconf, automake.
[arguments]: When cross-compile, add phase to fix rpl_malloc undefined references.
* gnu/packages/patches/m17n-lib-1.8.0-use-pkg-config-for-freetype.patch: New file.
