[Buildroot] [PATCH] package/gdb: update host gdb minimum host gcc version

[Romain Naour]

Following gdb 7.12.1 removal [1] the host gcc version needs
to be updated since gdb >= 8.x now requires C++11 compiler.

While at it, move BR2_HOST_GCC_AT_LEAST_4_8 under
BR2_PACKAGE_HOST_GDB since it's not an architecture
dependency. Add a comment when the host gcc is too
old to build host gdb.
