  This also needs to be added to the comment below:

comment "libunwind needs a toolchain w/ threads, dynamic library, gcc >= 4.9"
	depends on BR2_PACKAGE_LIBUNWIND_ARCH_SUPPORTS
	depends on !BR2_TOOLCHAIN_HAS_THREADS || BR2_STATIC_LIBS || \
		!BR2_TOOLCHAIN_GCC_AT_LEAST_4_9

  Applied to master with that fixed, thanks.

  Regards,
  Arnout
