package/gdb: update host gdb minimum host gcc version

Following gdb 7.12.1 removal [1] the host gcc version needs to be updated
since gdb >= 8.x now requires a C++11 compiler (gcc >= 4.8).

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.
