+Subject: [PATCH] extensions: added AR substitution
+
+This is to ensure that the correct AR is run in cross-compile jobs.
+Often a cross-compile build will succeed without this change but it
+fails on my Gentoo Linux system when I have binutils installed with the
+"multitarget" USE flag.
+This change substitues AR with the autotools-supplied AR for the
+extensions subdirectory.
