> Although support/dependencies/dependencies.sh checks for the version of make,
> this script doesn't get a chance to run if make encounters a syntax error as a
> result of being too old.
> 
> For example, the following syntax is only supported from make 3.81 onwards:
> 
> ifeq ($(BR2_TOOLCHAIN_BUILDROOT),y)
> include toolchain/toolchain-buildroot.mk
> else ifeq ($(BR2_TOOLCHAIN_EXTERNAL),y)
> include toolchain/toolchain-external.mk
> else ifeq ($(BR2_TOOLCHAIN_CTNG),y)
> include toolchain/toolchain-crosstool-ng.mk
> endif
> 
> This patch adds a check for the version of make very early in the Makefile, so
> that old make versions are handled gracefully.
