Bug#688246: qgis fails to build on powerpc due to internal spatialite

[David Matthew Mattli]

Package: qgis
Version: 1.7.4+1.7.5~20120320-1.1
Severity: important

Dear Maintainer,

qgis currently fails to build on powerpc. The problem seems to be
the src/core/spatialite/spatialite.c file which somehow makes
gcc emit code that the assembler rejects. I have two powerpc
systems that I've reproduced the problem on. They have identical
output to buildd log:
https://buildd.debian.org/status/fetch.php?pkg=qgis&arch=powerpc&ver=1.7.4%2B1.7.5~20120320-1.1&stamp=1337680851

I tried to build with both gcc-4.6 and gcc-4.7 but get the 
same errors.

qgis has libspatialite-dev as a build-dep and libspatialite3 as
a depedency of the binary package, through libgdal1, so why not
use the external libspatialite ?

I removed the comment from the line
       CMAKE_OPTS += -D WITH_INTERNAL_SPATIALITE=FALSE
in the debian/rules file and the package builds fine.

The maintainers of qgis say that the amalgamated version of 
spatialite.c included with qgis is mainly for windows support:

This is the section I changed:
