support/scripts/gen-bootlin-toolchains: generate BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard

Browse Source 
Previously, gen-bootlin-toolchains did not add a `depends` guard to
limit the available toolchains based on the minimum required GCC version
for the user selected CPU tuning.

Now, the proper BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard will be added based
on the version of GCC provided by the toolchain.
