+Subject: [PATCH] arm: fix static linking issues
+
+As reported by Buildroot developers these files causing static
+linking issues. The original contribution with the ARM unwind-resume
+rework and GNU libc sync was made before the combined libc change.
+But the patch was applied later, after the libc change and
+it seems the test coverage for static linking didn't catch it in
+the regression testing. Remove the files.
