[syslinux] Crosscompilation support status?

[Michal Suchánek]

Hello,

I see that in 6.04-pre3 there is some support for host and target gcc.

However, build always fails when using a cross-compiler:

[   89s] + make CC=x86_64-suse-linux-gcc CC_FOR_BUILD=gcc
...
[  401s] objcopy --strip-debug --strip-unneeded libutil.elf libutil.c32

This compiles a library file using syscalls (termios) with target gcc,
that's not going to work.

Is this expected to work by now or is more build system restructuring
needed?

Thanks
