+# Checks we do:

+#  -Check the RUNTIME path for the $TMPDIR
+#  -Check if .la files wrongly point to workdir
+#  -Check if .pc files wrongly point to workdir
+#  -Check if packages contains .debug directories or .so files
+#   where they should be in -dev or -dbg
+#  -Check if config.log contains traces to broken autoconf tests
+#  -Ensure that binaries in base_[bindir|sbindir|libdir] do not link
+#   into exec_prefix
+#  -Check that scripts in base_[bindir|sbindir|libdir] do not reference
+#   files under exec_prefix
