build: add xargs as prerequisite
Build system needs an 'xargs' that supports '-r' which darwin doesn't. Homebrew installs a 'gxargs' with the findutils package so look for 'gxargs' as well as 'xargs' This is a bit of a 'fun' corner case anyway. xargs is only required by the build if 'CONFIG_AUTOREMOVE' is set and after the build system has built 'tools/findutils' we have a fully working xargs for host anyway. Until that time we have to rely on the host's xargs implementation. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
