- set PYTHON variables using python-config on SLED11 because the pkg-config
files are not there
- set the PYTHON variables only in the main libreoffice.spec because
they are not needed to build help
- build-link-rt.diff: liblt is linked with librt, so we need to link
the libmerged with librt as well; it fixes the build on SLED11
- use -g1 instead of -g to reduce the memory and disk usage with
debugging symbols; note that only .o files need about 12GB when
compliled with full debugging symbols
