[ Upstream commit b2accfe7ca5bc9f9af28e603b79bdd5ad8df5c0b ]
Commit 579aee9fc594 ("powerpc: suppress some linker warnings in recent linker versions") enabled support to add linker option "--no-warn-rwx-segments", if the version is greater than 2.39. Similar build warning were reported recently from linker version 2.35.2.
ld: warning: arch/powerpc/boot/zImage.epapr has a LOAD segment with RWX permissions ld: warning: arch/powerpc/boot/zImage.pseries has a LOAD segment with RWX permissions
Fix the warning by checking for "--no-warn-rwx-segments" option support in linker to enable it, instead of checking for the version range.
