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 ```
