[OE-core] [PATCH 1/4] u-boot: Add missing dependency on swig

[Martin Jansa]

FWIW: my do_compile_prepend hack to stop autodetecting swig from sysroot
(in pre-RSS - recipe specific sysroots in Yocto 2.2) stopped working in
2017.07 version where it was moved from tools/Makefile:
https://github.com/u-boot/u-boot/commit/727f153629719c93f9c5df6e391fdfee32377ca7#diff-c9b3e9a4c86396781af56d6bdfc8c9f3

It was still building without swig I belive until 2018.07 version which
doesn't use "$(if $(shell which swig 2> /dev/null)" to check for native
swig anymore since:
https://github.com/u-boot/u-boot/commit/15b97f5c5e6d88e0560c6928f3acd01c999a494d#diff-c9b3e9a4c86396781af56d6bdfc8c9f3

Thanks Joshua for the fix.
