Yeah, that did the trick!

I cannot compile code without
TARGET_CFLAGS='-ftrampolines -fno-stack-protector' -- more precisely, without
trampolines. Configure fails with this message:
...
checking whether `gcc' generates calls to `__enable_execute_stack()'...
configure: error: gcc failed to produce assembly code
The message from config.log says:
conftest.c: In function 'g':
conftest.c:282: error: trampoline code generation is not allowed
without -ftrampolines
configure:20492: $? = 1
configure:20496: error: gcc failed to produce assembly code
If I configure without -ftrampolines in CFLAGS, configure finishes just OK,
but compilation later fails:

So for proper compilation I _have_ to pass -ftrampolines in both CFLAGS and
TARGET_CFLAGS.
By the way, is there any way to define which GRUB modules to build?
Right now I get a compile error on squash4_module, which I'm not going to use
anyway...
The compile error is as follows:
