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.]
