PowerPC Packages

[Nathan Whitehorn]

Over the last few weeks (2 cores makes the build take a long time!), 
I've built a complete set of 32-bit PowerPC packages for 10-STABLE, 
which can be found at 
http://people.freebsd.org/~nwhitehorn/powerpc-10-packages. This address 
can be used as a pkg repository, but also contains a post-mortem of what 
fails to build and why if you look at it in a web browser, which may be 
of interest to porters. Note that these packages are unofficial and so 
are accompanied by no guarantees whatsoever from anyone. The packages 
are still slowly uploading, but the logs and debug information are there 
already.

Over all, 19443 ports succeeded. 1116 failed for some reason (this 
number includes things marked BROKEN) and 3867 didn't start because 
ports they depend upon failed. The largest issues are Boost and QT4 
webkit. Boost has failed because it seems to unconditionally prefer 
clang to gcc when both are present. On PowerPC, both are installed but 
GCC remains the default due to some remaining issues with clang. Boost 
ignores the default, runs into the issues, and fails. Maybe it should be 
forced to use whatever "cc" is? Several other ports run into this issue. 
QT4 webkit seems to have caused GCC to segfault for some reason.

The website has a list of failed builds sorted by the number of ports 
they are blocking, both directly (ports with this ports in their 
*_DEPENDS line) and indirectly (all of those, plus all the ports that 
depend on this port's children). Also listed is the point at which the 
job failed and a link to the build log. "JOB_FAILURE" means that the 
build or packaging step failed. "PRE_SCRIPT_FAILURE" means that the job 
failed in the "make fetch" stage, which includes ports marked BROKEN.

I am more than happy to try out patches if porters without access to 
PowerPC systems want to fix any of these.
