Created attachment 448970 [details, diff]
sample patch for profiles/arch/amd64-fbsd/make.defaults

Compile is successful when you change to CFLAGS_x86_fbsd="-m32" from 
CFLAGS_x86_fbsd="-m32 -DCOMPAT_32BIT -B/usr/lib32 -L/usr/lib32".

Created attachment 448972 [details, diff]
sample patch for eclass/freebsd.eclass

Move a special 32bit CFLAGS for sys-freebsd/*.

I think it'd best to finally address this on the CMake end.

[Comment 4 Michał Górny 2016-12-22 15:21:25 UTC]

This should be solved on cmake-utils end now.
