CONFIG_JUMP_LABEL doesn't ensure HAVE_JUMP_LABEL, if it
is not the case use maintainers's own mutex to guard
the modification of global values.

CONFIG_JUMP_LABEL says the user wants to use jump labels.
But we also need the toolchain to support it.

That is reflected in CC_HAVE_ASM_GOTO=y, and if both are
set then HAVE_JUMP_LABEL is set to true.

Please resubmit and update the changelog to reflect this,
e.g. add something like

Use HAVE_JUMP_LABEL as elsewhere in the kernel to ensure
that the toolchain has the required support in addition to
CONFIG_JUMP_LABEL being set.
