package/gcc/Config.in.host: hide gcc version for unsupported CPUs
When a new gcc version is introduced, for example gcc 15 in
commit [1], it should have also added a "depends on
!BR2_ARCH_NEEDS_GCC_AT_LEAST_15" to the previous gcc version.
This logic is described for external toolchains in commit [2],
for example. The internal Buildroot toolchains should have the
same logic. This logic existed for previous gcc version. See for
example the removal of gcc 12 in commit [3].
There is usually no problem, because all the three latest active gcc
versions supports all CPUs present in Buildroot.
However, the commit [4] recently added the support for the Arm
Cortex-A720 CPU, which needs at least gcc 14. Since there is no
logic preventing the selection of the gcc version, it is possible
to select an unsupported gcc version (i.e. gcc 13).
In such a case, the host-gcc-initial package configuration fails
with output:
Unknown cpu used in --with-cpu=cortex-a720
This commit fixes the issue by adding those missing dependencies.
