+Subject: [PATCH] Add stack markings for GNU to fmod assembly files
+
+This adds stack markings to the missing fmod .S files, otherwise the
+final libopenlibm object file gets marked with an executable stack.
+
+Output when compiling from source on Gentoo Linux:
+
+```
+ * QA Notice: The following files contain writable and executable sections
+ *  Files with such sections will not work properly (or at all!) on some
+ *  architectures/operating systems.  A bug should be filed at
+ *  https://bugs.gentoo.org/ to make sure the issue is fixed.
+ *  For more information, see:
+ *
+ *    https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart
+ *
+ *  Please include the following list of files in your report:
+ *  Note: Bugs should be filed for the respective maintainers
+ *  of the package in question and not hardened@gentoo.org.
+ * RWX --- --- usr/lib64/libopenlibm.so.4.0
