binutils: revert to version 2.25.1 for e500mc targets

Poky master branch has recently upgraded to binutils version 2.26,
but for e500mc based targets the kernel crashes early in boot if
built with this version of binutils.

Reverting back to binutils 2.25.1 is a temporary workaround to
be able to build bootable images for these targets.

+Subject: [PATCH 05/13] 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.
