Indeed. Due to this, perhaps there's a bunch of NPTL dependencies we
could remove:

package/blktrace/Config.in:     depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL # clock_nanosleep()
package/can-utils/Config.in:    depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL # clock_nanosleep()
package/dvblast/Config.in:      depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL # clock_nanosleep()
package/nilfs-utils/Config.in:  depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL # clock_nanosleep()

Anyway, for this linuxptp change, I have marked the patch as "Delegated
to Peter" on patchwork, so that Peter takes care of it.

Best regards,

Thomas
