sigset_t was added to kerbel 6.9 with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=487fa28fa8b60417642ac58e8beda6e2509d18f9
Reason:
The util-linux debian package fails to build on parisc, because
sigset_t isn't defined in asm/signal.h when included from userspace.
Move the sigset_t type from internal header to the uapi header to fix the
build.

Note: other platforms had sigset_t defined in asm/signal.h.
Maybe sigset_t needs to be removed from klibc/include/arch/parisc/klibc/archsignal.h ?
