Thomas Petazzoni eab17d763c arch/Config.in: introduce BR2_ARCH_NEEDS_GCC_AT_LEAST_14
Since commit
a0d2a5cfec ("support/scripts/gen-bootlin-toolchains:
generate BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard"), the
gen-bootlin-toolchains script will generate references to
BR2_ARCH_NEEDS_GCC_AT_LEAST_X including potentially against the "next"
version of gcc.

Indeed, a toolchain using gcc 13.x should have a "depends on
!BR2_ARCH_NEEDS_GCC_AT_LEAST_14" so that once some architectures that
require gcc 14.x are added, such toolchains are not made visible.

In order for this to work, we must have the
BR2_ARCH_NEEDS_GCC_AT_LEAST_x symbol ready for the N+1 version of gcc
compared to the latest one we support.

As we're supporting up to gcc 13.x right now, let's introduce the
symbol BR2_ARCH_NEEDS_GCC_AT_LEAST_14 so that gcc 13.x toolchains can
be marked depends on !BR2_ARCH_NEEDS_GCC_AT_LEAST_14.

The other alternative would be to make the gen-bootlin-toolchains a
bit smarter, and not emit this depends on
!BR2_ARCH_NEEDS_GCC_AT_LEAST_14 if BR2_ARCH_NEEDS_GCC_AT_LEAST_14 does
not exist. But this would require re-running the script when
BR2_ARCH_NEEDS_GCC_AT_LEAST_14 which we are unlikely to do. While
today, when the script is invoked, the usual check-symbols complains
and reminds us that BR2_ARCH_NEEDS_GCC_AT_LEAST_14 should be added, so
we remember to do it right away.
