toolchain-external: add support for gcc version dependency
This commit wires up the gcc version dependency mechanism in the external toolchain backend. To do so, it: * Changes the definition of all pre-defined external toolchain profiles to select the appropriate BR2_TOOLCHAIN_GCC_AT_LEAST_* option. * For custom external toolchains, provides a visible Config.in "choice" to select the gcc version used in the external toolchain. * Adds a new check_gcc_version function, that verifies that the real gcc version found in the external toolchain matches the one declared in the Buildroot configuration. [Thomas: use better sed expression proposed by Yann E. Morin, which works with more cases.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
