[Debian-med-packaging] Bug#989051: mrc: FTBFS on hppa - obj/mrc_rsrc.o created with wrong OS/ABI

[Maarten L. Hekkelman]

Dear Dave,

Thanks for reporting, and apologies for not responding earlier.

I found the underlying problem, apparently the ABI field of the ELF 
header should contain a flag indicating it is a Linux executable. In 
order to set this flag properly, I need to find out various things and 
perhaps it is easiest to try to figure out these myself. Is it possible 
to get access to a HPPA machine running Debian? I am a Debian 
maintainer, if that makes any difference.

Otherwise, could you provide me the output of `cpp -dM /dev/null` and 
perhaps also how to detect PA-RISC/Debian in a cmake file. That last 
question is perhaps a bit too much to ask for, but any hint is appreciated.

regards, -maarten
