The problem you are seeing comes from the last line - you are asking 
OMake to build fooTest executable, which will always be built to "best 
code". In other words, all the rules needed to build both are there, but 
you never ask for the actual target. A more flexible alternative for the 
above OMakefile snippet is the following:

LIB = foo
all: $(OCamlLibrary $(LIB),$(LIBFILES))
all: $(OCamlProgram fooTest, fooTest $(LIB))

This should do the right thing for any combination of 
BYTE_ENABLED/NATIVE_ENABLED - the OCamlLibrary and OCamlProgram 
functions return the list of all the targets that they know how to build.
