+Subject: [PATCH] configure: do not configure in menuselect
+
+When cross-compiling, the arguments and environment for ./configure are
+different for the host and the target, and we want menuselect to be
+compiled for the build machine, not the target.
+
+Although we do not pass any option to ./configure for menuselect, the
+environment may still reference variables for the target, like CC or
+CFLAGS and so on... We can not build menuselect with those variables.
+
+Instead, just assume that menuselect will be pre-compiled.
+
