This is with uclibc, binutils-uclibc and binutils-gcc, with the use of
cross-compiling using --target= from configure. This label is added
via /usr/lib/*.o (crt1.o and friends), but the uclibc toolchain
uses /usr/x86_64-unknown-linux-uclibc/lib/*.o, which doesn't contain
that label. So that clarifies the difference.
