Hm, maybe those should be conditional

[alexmyczko]

same with debian: https://buildd.debian.org/status/package.php?p=libtree&suite=sid

[haampie]

@ismaell / @iluceno do you have a suggestion for a bmake compatible way to test for say -m32 / -m64 flag support? I don't want to add a configure script. If it's not easy then I'll just stick to gmake for make check targets.

[ncopa]

are there any architectures other than x86_64 that supports multilib with -m32/-m64?

[ismaell]

I'm not sure it makes sense to test for a flag, shouldn't it just explicitly test all the supported ISAs on all the architectures?

[ismaell]

I'll try to come up with a solution compatible with cross-compiling tonight.
