[Buildroot] [PATCH v2 1/3] acl: make sure build picks up TARGET_CFLAGS

[Buildroot] [PATCH v2 1/3] acl: make sure build picks up TARGET_CFLAGS

[Arnout Vandecappelle]

The acl build system doesn't use automake, therefore it is broken. It
doesn't use the CFLAGS passed by configure. Work around this by passing
CFLAGS in the environment. The makefiles append to CFLAGS, so this
works.

This issue hasn't led to build failures, but it is visible e.g. when
stack protector is enabled: the stack protector options are not applied
to acl. Also debug and optimisation options aren't applied.

[Buildroot] [PATCH v2 2/3] acl: add host variant

[Arnout Vandecappelle]

We need host-acl to fix issues with fakeroot.

Unfortunately, all the hacks (except the .la fixup) have to be repeated.

[Buildroot] [PATCH v2 3/3] fakeroot: depend on acl

[Arnout Vandecappelle]

Recent versions of fakeroot have grown support for acl. We don't really
need this since we don't use acls in Buildroot. However, it turns out
that "cp -a" does something funky with acls, with the result that
fakeroot without acl support looses the ownership and permissions on
the copied file. "cp -a" may be (is even likely to be) used in a
BR2_ROOTFS_POST_FAKEROOT_SCRIPT, so we need to support this.

Note that host-acl itself depends on host-attr, so this pulls in two
extra packages in each build. The impact on build time is about 10s.

 You can formalize this by replying with

 Tested-by: Andreas Naumann <dev@andin.de>

(but then without a space in front). It gets picked up by Patchwork and it will
be added to the git log.

 By the way, did you actually test *this patch*, or just that fakeroot works
after the entire series is applied? In the latter case, you should only add your
Tested-by to the last patch (and perhaps 2/3). This particular patch has no
impact on fakeroot.

 Arnout

I guess too late now. Will do next time.

I did test this patch in in so far that host-acl successfully builds 
without the attr/xattr.h header being picked up from the host machine. 
And of course subsequently that fakeroot with acl works as expected.

Andreas

 My point is: this patch is about target-acl, not host-acl, that's why I asked.
So you didn't actually test this patch :-)
