$ git grep "select BR2_PACKAGE_BINUTILS"
package/dropwatch/Config.in:	select BR2_PACKAGE_BINUTILS
package/oprofile/Config.in:	select BR2_PACKAGE_BINUTILS

So we need it for dropwatch and oprofile. In fact, what is needed is
not the full binutils (i.e the binutils programs), but the libbfd
library which is part of the binutils tarball.

Best regards,

Thomas
