csky fails to build libgcc after the c23 changes because it has a
typedef for bool. AFAICT it's internal to the file, so removing the
typedef isn't an ABI change.
Similiarly for c6x which includes unwind-arm-common.inc. I suspect
most, if not all of the arm-v7 and older targets are failing to build
right now.
I've built and regression tested both csky-linux-gnu and c6x-elf with
this change. OK for the trunk?

libgcc/
* config/csky/linux-atomic.c (bool): Remove unnecessary typedef.
* unwind-arm-common.inc (bool): Similarly.
