+Subject: [PATCH] Make dynamic linker a relative symlink to libc
+
+absolute symlink into $(libdir) fails to load in a cross build
+environment, especially when executing qemu in usermode to run target
+applications, which cross build systems often do, since not everything
+can be computed during cross builds, qemu in usermode often comes to aid
+in such situations to feed into cross builds.
+
+V2:
+ Make use of 'ln -r' to create relative symlinks, as most fo the distros
+ shipping coreutils 8.16+
