What

The new guest_module_dir host fixture in upstream #6106 is built as a synthetic ELF without PT_GNU_STACK. On this Linux host, the loader treats it as requesting an executable stack and refuses to load libOptional.prx, so the test fails before checking the intended dependency behavior. This follow-up appends a PT_GNU_STACK header with read/write flags and increments the ELF program-header count. It changes only the test fixture; production relinker code is unchanged.

This draft branch contains boykopovar#6106's current project-source commit, preserving Zinebyte's authorship, followed by my two-line fixture commit. Depends on: boykopovar#6106. The fixture commit should be taken after boykopovar#6106 or incorporated into it; the branch is not an independent implementation of its dependency change.

Tested

Linux x86-64, current main d92a8dad390af1807cc91622b924252141816a5a, Release relinker-only build. With boykopovar#6106 head 78b906fb67a8edff3969f60d26ced129f981139e alone, guest_module_dir fails deterministically because ctypes.CDLL reports libOptional.prx: cannot enable executable stack as shared object requires: Invalid argument. With only this fixture correction added, 172/172 CTests pass, including guest_module_dir (0.28 s). Conventions and whitespace checks pass.

I also composed the current boykopovar#6106 change with #5559 on the same main. Without this correction, 172/173 relinker tests pass and guest_module_dir fails with the same loader error; with it, 173/173 pass, including guest_deferred_dependencies. These are local relinker-only checks; a full project build and other hosts remain unverified.
