Ah, right, the rule that rebuilds the libraries does not work correctly
for more than one library because I do pass "$^" there which is the list
of directories and not a single directory.

As a quick hack this should fix it:

diff --git a/include/mk/testcases.mk b/include/mk/testcases.mk
index 684655fbf..7e0ec13f9 100644
--- a/include/mk/testcases.mk
+++ b/include/mk/testcases.mk
@@ -49,7 +49,9 @@ LTPLIBS_FILES = $(addsuffix .a, $(addprefix $(abs_top_builddir)/libs/, $(foreach
 MAKE_DEPS += $(LTPLIBS_FILES)
 
 $(LTPLIBS_FILES): $(LTPLIBS_DIRS)
-       $(MAKE) -C "$^" -f "$(subst $(abs_top_builddir),$(abs_top_srcdir),$^)/Makefile" all
+       for dir in $^; do \
+               $(MAKE) -C "$$dir" -f "$(subst $(abs_top_builddir),$(abs_top_srcdir),$$dir)/Makefile" all; \
+       done
 
 LDFLAGS += $(addprefix -L$(top_builddir)/libs/lib, $(LTPLIBS))


This does not parallelize the build but I guess that it would be fine since
when we rebuild LTP from top directory the libraries are build first anyways
and this is no-op.
