Subject: [PATCH] [RFA] Fix csky and c6x build failures

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?

	PR target/117628
libgcc/
	* config/csky/linux-atomic.c (bool): Remove unnecessary typedef.
	* unwind-arm-common.inc (bool): Similarly.
