[oe] mesa depending on samba or samba depending on extern talloc?

[Martin Jansa]

On 2010-10-20 I've pushed newer mesa-7.9
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=30a3ea891d4511059a51882674f33aff2dddb96e
which depends on talloc
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=fabce288e40037d28c70f0f034185176f85e8664
and separate talloc recipe (because building whole samba just to provide talloc for mesa seems wrong
and samba produced ICE before khem's fix) 
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=afce52663d6b5b79c097136fa794dd3f76a4afff

Today I noticed, that usr/lib/pkgconfig/talloc.pc from talloc recipe was enough for mesa to compile, 
but because there was no libtalloc.so link it wasn't used in the end (as ldd confirms).

so talloc stages:
bitbake at jama ~ $ ll tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.*
-rwxr-xr-x 1 bitbake bitbake  32K Dec 21 13:30 tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.a
-rwxr-xr-x 1 bitbake bitbake  73K Dec 21 13:30 tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.so.2.0.1
bitbake at jama ~ $ ll tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/pkgconfig/talloc.pc
-rw-r--r-- 1 bitbake bitbake 251 Dec 21 13:30 tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/pkgconfig/talloc.pc

samba adds:
bitbake at jama ~ $ ll tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.*
lrwxrwxrwx 1 bitbake bitbake   14 Dec 14 13:33 tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.so -> libtalloc.so.1
-rwxr-xr-x 1 bitbake bitbake 123K Dec 14 13:33 tmpdir-shr/sysroots/armv4t-oe-linux-gnueabi/usr/lib/libtalloc.so.1

now for sure I don't want to install whole samba on target (just for libtalloc) so I have few options

1) fix talloc to install libtalloc.so -> libtalloc.so.2.0.1 (conflicts with samba in sysroot)
2a) move libtalloc to separate package in samba recipe and make mesa depending on samba
2b) move libtalloc to separate package in samba recipe in case someone builds 
    it before mesa, but still depend only on fixed talloc
3) fix talloc + force samba build to use already installed libtalloc instead of building own version

Option 3) looks best, but I'm not sure how tightly samba depends on talloc 
and don't have time to test all samba versions we currently have
(3.0.23c, 3.0.34, 3.2.15, 3.3.0, 3.3.9, 3.5.6), so 2b) looks as easier fix.

CCed 2 samba maintainers (wrt MAINTAINERS file) or if there is someone who cares about samba
recipes: can you clean recipes/samba a bit and provide some feedback on talloc issue?
