Adding INSTALL_MOD_PATH should normally not be necessary, since
LINUX_MAKE_FLAGS already contains INSTALL_MOD_PATH.

>From linux/linux.mk:

LINUX_MAKE_FLAGS = \
        HOSTCC="$(HOSTCC)" \
        HOSTCFLAGS="$(HOSTCFLAGS)" \
        ARCH=$(KERNEL_ARCH) \
        INSTALL_MOD_PATH=$(TARGET_DIR) \
        CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)" \
        DEPMOD=$(HOST_DIR)/sbin/depmod

Macro, can you post your current package (.mk file and Config.in files,
or even better, a patch against Buildroot), so that we can potentially
reproduce your issue and help you solve it?

Best regards,

Thomas
