In principle the recursive make invocation should set
CXXFLAGS=$(CXXFLAGS_FOR_TARGET) already:
maybe-all-target-libgcobol:
TARGET-target-libgcobol=all
maybe-all-target-libgcobol: all-target-libgcobol
all-target-libgcobol: configure-target-libgcobol
@: $(MAKE); $(unstage)
@r=`${PWD_COMMAND}`; export r; \
s=`cd $(srcdir); ${PWD_COMMAND}`; export s; \
$(NORMAL_TARGET_EXPORTS) \
(cd $(TARGET_SUBDIR)/libgcobol && \
$(MAKE) $(BASE_FLAGS_TO_PASS) $(EXTRA_TARGET_FLAGS) \
$(TARGET-target-libgcobol))
and EXTRA_TARGET_FLAGS includes
'CXXFLAGS=$$(CXXFLAGS_FOR_TARGET)' \
Some Makefile.am have sth like the following (but not libgomp for example):
# Work around what appears to be a GNU make handling MAKEFLAGS
# values defined in terms of make variables, as is the case for CC and
# friends when we are called from the top level Makefile.
