buildroot: use nm compiled in buildroot

Remove binaries/usr/lib/libbfd-2.21.1.so and /usr/bin/nm from the repo. Instead use the compiled versions in buildroot. Patch the installation rule to install only "nm", when PACKAGE_BINUTILS_TARGET is not used(!). libbfd-2.21.1.so is installed by default by the installation rule of PACKAGE_BINUTILS. Binary nm was added in the commit: d2a486cc rootfs_override: add /usr/bin/nm and its libbfd Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

+Subject: [PATCH] package/binutils: install nm on the target
+
+We don't need other binaries from the binutils package for wr-switch.
+Library needed by nm (libbfd-2.24.so) is installed when BR2_PACKAGE_BINUTILS is
+selected.
