Config.in: add symbols for BR2_HOST_GCC_AT_LEAST_X_Y
Some host packages need a recent gcc version. Add symbols to Config.in to specify the HOSTCC version. The values are passed through the environment, and this environment is generated in a new support script. Also update the documentation to mention the new symbols. [Thomas: simplify by using only make logic instead of an external shell script.] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
