Oops. Misassumption on my side. I just saw the defines on the compile
command line:

-DLINUXBIOS_LINKER='"GNU ld version 20030722 (SuSE Linux)"' -DLINUXBIOS_ASSEMBLER='"GNU assembler version (x86_64-suse-linux) using BFD version 20030722 (SuSE Linux)"'

Are these compiled in per default?

Hm. We're setting a lot of default options in and some in for the mainboards.. Is there room to place defaults for these
specifics in there?

-at doesn't seem to work btw. -a -t does though.. whatever.

so far I deleted the linuxbios-builds directory most of the time before each
build to make sure nothing old is keeping things from building
correctly because I saw a place or two where things did not get rebuild
though something changed in the source tree. With the rebuild of all
motherboards currently being around 10 minutes on this machine speed did
not really care for generating the reports along. This is different if
the tool is used actively in each cycle during development..

Oh,.. I had that problem too with the -t option.. Thanks for fixing
this. I will remove the stupid tr -d workaround I used.
