Hi Felipe
Besides, I found another 2 issues:
1. some head files are missing after fetching the liblua src codes

total 28

I guess something wrong in Makefile.uk

This is actually a problem of the build system, we're currently working on it.
As a workaround, in your app's Makefile please put:
all:
@make -C $(UK_ROOT) A=$(PWD) L=$(LIBS) fetch
@make -C $(UK_ROOT) A=$(PWD) L=$(LIBS) prepare
@make -C $(UK_ROOT) A=$(PWD) L=$(LIBS)
This will make sure the prepare step runs before the actual make, which is
what's causing the error.
2. seems liblua can't be built with nolibc enabled, no signal.h is found
Yes, one of the commits says it, this library can't build against noblic (at
least for now), it requires newlib.
3, with newlib enabled, the helloworld app (almost dummy main()) can't
be linked:

This is strange. Most of the symbols are newlib ones, did you do a properclean;
make and you still get these errors? I ask becase I have all of those symbols
in my final image...
