[Qemu-devel] [PATCH 00/14] configure: --with-confsuffix option

[Eduardo Habkost]

This series is the third version of the --confsuffix/--confdir changes I have
submitted before. Now it does two interface changes:

 - Changes --datadir meaning to match Autoconf convention
   (meaning that it should point to /usr/share, not /usr/share/qemu).
   NOTE: this breaks compatibility.
   I don't know of anybody who uses that option today. Neither Fedora, Debian,
   Arch Linux, Gentoo, or FreeBSD use it[1].
 - Add --with-confsuffix option, to allow the /etc/qemu and /usr/share/qemu
   directories to have a different names.

Most of the patches are variable renames and cleanups. The actual changes are
only on the last 2 patches.

First, internal configure variables are renamed, without changing
config-host.mak:

  configure: rename $datadir to $qemu_datadir
  configure: rename $docdir to $qemu_docdir
  configure: rename $confdir to $qemu_confdir

Then create_config gets ready for config-host.mak variable renames
(Qemu-specific directories will now have a "qemu_" prefix):

  create_config: separate section for qemu_*dir variables

Then, variables are renamed on config-host.mak and Makefiles:

  config-host.mak: rename datadir to qemu_datadir
  config-host.mak: rename confdir to qemu_confdir
  Makefile: use $(qemu_confdir) instead of $(sysconfdir)/qemu
  config-host.mak: rename docdir to qemu_docdir
  config-host.mak: remove CONFIG_QEMU_SHAREDIR
  config-host.mak: reorder variables a bit

Then old code on create_config is removed:

  create_config: remove *dir block
  create_config: simplify prefix=* block, remove CONFIG_QEMU_PREFIX

Finally, the user-visible changes:

  configure: change meaning of --datadir to Autoconf convention
  configure: add --confsuffix option
