[yocto] u-boot recipe: Missing dependencies

[Martin Jansa]

Be aware that when you provide python-native, it's more likely that
swig-native will be detected in sysroot as well and then u-boot will fail
to build libfdt python library.

To prevent this autodetection you can use something like this:

do_compile_prepend () {
    sed 's@\(^always += $(if $(shell which swig 2>
/dev/null),_libfdt.so)$\)@# do not autodetect swig, there is no swig-native
dependency \1 at g' -i ${S}/tools/Makefile
}

which isn't needed in Yocto 2.3 Pyro and newer thanks to RSS and HOSTTOOLs
filtering.
