Inter-OS Cross-compilation - pkgsrc gmake/GCC problem

[pl <pl%szwajn.net@localhost>]

Hi,
Having a hard time cross-compiling pkgsrc gtk2/3 on FreeBSD x86_64 box for an x86 NetBSD machine. Specifically, pkgsrc tries to build gmake and gcc6 which seems to be broken on FreeBSD (random circular dependencies)

I know that HOWTO-use-crosscompile says cross-compilations are currently NetBSD-NetBSD only, but with some messing (primarily with mk.conf) I managed to build some working packages that don't need gmake/gcc6 on build-time (figlet, doas etc.), so maybe it's possible to build that gtk as well...

Is there way to make gcc6 build or, even better, avoid building it at all (since I have already both "native" gcc and a working toolchain from build.sh)?

My full mk.conf:
.ifdef BSD_PKG_MK	# begin pkgsrc settings

.endif			# end pkgsrc settings



System gcc version is 13.3.0, and with it I made both toolchain and 10.1 release
