[Buildroot] [PATCH 1/2] package: acpica: Add host buildling support

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

Commit titles should have prefixes that look like:

	acpica:

or:

	package/acpica:

and not:

	package: acpica:

Yes, that's a silly convention, but conventions are always silly :)

This should have reference the autobuilder issue that it helps fixing
(even if it's only part of the fix).

Weird that you put the host build command before the target build
command, and then the host install command *after* the target install
command. So I've reordered this.

DESTDIR="$(HOST_DIR)" is wrong, so I've replaced with
PREFIX="$(HOST_DIR)/usr". See
https://stackoverflow.com/questions/11307465/destdir-and-prefix-of-make
for a quick explanation about the difference.

Applied to master with those changes. Thanks!
