The problem is that CFLAGS leak into target. Default compilation
command used by automake is

COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \
        $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)

And any initial CFLAGS setting is passed through to all generated
Makefiles. 

So instructions in INSTALL are, unfortunately, wrong - CFLAGS cannot be
safely used to initialize host environment.
