[PATCH v3 1/5] gdbstub: Expose TARGET_SIGTRAP in a target-agnostic way

[Ilya Leoshkevich <iii@linux.ibm.com>]

The upcoming syscall catchpoint support needs to send SIGTRAP stop
packets to GDB. Being able to compile this support only once for all
targets is a good thing, and it requires hiding TARGET_SIGTRAP behind
a function call.
