Rather than adding this in the package's Makefile, can't we just do the
installation manually in the .mk file, that is, something like:

    ifeq ($(BR2_STATIC_LIBS)$(BR2_SHARED_STATIC_LIBS),y)
    define LEVELDB_INSTALL_STATIC
        $(INSTALL) -D -m 0644 $(@D)/lib/libleveldb.a $(1)/usr/lib/libleveldb.a
    endef
    endif
    ifeq ($(BR2_SHARED_LIBS)$(BR2_SHARED_STATIC_LIBS),y)
    define LEVELDB_INSTALL_SHARED
        $(INSTALL) -D -m 0644 $(@D)/lib/libleveldb.so $(1)/usr/lib/libleveldb.so
        ln -sf libleveldb.so $(1)/usr/lib/libleveldb.so.VERSION
    endef
    endif

    define LEVELDB_INSTALL_STAGING_CMDS
        $(call LEVELDB_INSTALL_STATIC,$(STAGING_DIR))
        $(call LEVELDB_INSTALL_SHARED,$(STAGING_DIR))
        install -D -m 0644 $(@D)/leveldb.h $(STAGING_DIR)/usr/include/leveldb.h
    endef

    define LEVELDB_INSTALL_TARGET_CMDS
        $(call LEVELDB_INSTALL_SHARED,$(STAGING_DIR))
    endef

(to be adapted to the real file names, of course))

I think this would not be needed if you do:

    define LEVELDB_BUILD_CMDS
        $(TARGET_MAKE_ENV) $(TARGET_CONFIGURE_OPTS) $(MAKE) \
            $(LEVELDB_MAKE_ARGS) -C $(@D)
    endef

i.e. pass the TARGET_CONFIGURE_OPTS in the environment, and not as make
arguments.

To be tested and confirmed, of course.

I would prefer we actually we use direct logic, like:

    ifeq ($(BR2_STATIC_LIBS),)
    LEVELDB_MAKE_ARGS += SHARED=
    endif

    ifeq ($(BR2_SHARED_LIBS),)
    LEVELDB_MAKE_ARGS += LIBRARY=
    endif

Here switch the order of TARGET_CONFIGURE_OPTS, like explained above.

And adapt the install commands as explained above.
