Which version of FPC are you using? We have been adding the "do not create an executable stack" section to ELF files since FPC 2.2.4 already.

The default of the GNU binutils is "create an executable stack". The object files have to contain a special section for it to be disabled.

Update your FPC version. There's also a linker parameter that you can use, but that's not the recommended approach.
