Overloading `build_style` for meta-packages has always felt very hacky,
and it prevents having the main package be a meta-package (with non-meta
subpackages) and using a `build_style` at the same time (example of
trying to hack around that: 62c0c08e18).
It also can create confusion about how subpackages work if you can
define a `build_style` there (but only `meta`).
This makes using `build_style=meta` an error at the package and subpackage
level, and replaces it with a new variable (`metapackage=yes`).
A pkglint for non-empty meta-packages is also added.
BUILD STYLES ============ These shell snippets provide support for multiple build systems, i.e GNU configure, CMake, etc. A build style file must provide at least the following functions: - do_configure - do_build - do_install If a source package defines its own do_xxx() function, the function defined in the build style file is simply ignored.
