hold all of the layers that we import with git-subtree.

+Subject: [PATCH 05/14] Explicitly link with libm on uclibc
+
+Description:
+
+We do not need to have the libtool patch anymore for binutils after
+libtool has been updated upstream it include support for it. However
+for building gas natively on uclibc systems we have to link it with
+-lm so that it picks up missing symbols.
