pkg-infra: add host-xxx-package macro
Create host-generic-package, host-autotools-package and
host-cmake-package macros. Such a macro is more intuitive to use than
the $(call ...,host) construct. Also it speeds things up by having
one less $(call ...) evaluation.
Also includes documentation update, but not for buildroot.html.
This brings the time for 'make -qp' (which is used by bash-completion)
down from 1.85s to 1.35s on my laptop.
