+Subject: [PATCH] botan.pro: pass QMAKE_AR
+
+* otherwise AR from environment sets it with cqs params, e.g.:
+  x86_64-oe-linux-ar cqs
+  from QMAKE_AR = ${OE_QMAKE_AR} cqs
+
+  but then botan's Makefile will add "crs" after it causing:
+  http://errors.yoctoproject.org/Errors/Details/194653/
+
+  x86_64-oe-linux-ar cqs crs libbotan-2.a build/obj/lib/botan_all.o build/obj/lib/botan_all_ssse3.o
+  x86_64-oe-linux-ar: libbotan-2.a: No such file or directory
+  Makefile:79: recipe for target 'libbotan-2.a' failed
+  make[4]: *** [libbotan-2.a] Error 1
+
+* add --ar-options parameter to botan configure and respect the
+  value when set (before cc.ar_options and osinfo.ar_options)
+  then use this to pass empty ar_options as we already include
+  the options in ar_command
