at least one typo is obvious in Build/source/m4/kpse-fontconfig-flags.m4:

  if test "x$with_fontconfig_libdir" != x; then
    kpse_cv_fontconfig_libdir="-L$with_fontconfig_libdir -lfontconfig"
  fi

should be

  if test "x$with_fontconfig_libdir" != x; then
    kpse_cv_fontconfig_libs="-L$with_fontconfig_libdir -lfontconfig"
  fi

because the below line uses kpse_cv_fontconfig_libs, but not kpse_cv_fontconfig_libdir:

LIBS="$kpse_cv_fontconfig_libs $LIBS"

this could explain why it failed when i used --with-fontconfig-includes
and --with-fontconfig-libdir; but would not explain why it failed when
it used pkg-config, which seems to be using the correct variable name.

Best,
