# gtk+ >= 3.10 can build a native version of gtk-update-icon-cache if
# --enable-gtk2-dependency=no is set when invoking './configure'.
#
# Unfortunately, if the target toolchain is based on uClibc, the macro
# AM_GLIB_GNU_GETTEXT will detect the libintl built for the target and
# will add '-lintl' to the default list of libraries for the linker (used
# for both native and target builds).
#
# But no native version of libintl is available (the functions are
# provided by glibc). So gtk-update-icon-cache will not build.
#
# As a workaround, we build gtk-update-icon-cache on our own, set
# --enable-gtk2-dependency=yes and force './configure' to use our version.
