* config/rs6000/t-ppccomm (MULTILIB_MATCHES_SYSV): Recognize
mcall-netbsd as a match for mcall-sysv.
(EXTRA_MULTILIB_PARTS): Add ncrti$(objext) and ncrtn$(objext).
(ncrti.S, ncrtn.S): New targets.
($(T)ncrti$(objext), $(T)ncrtn$(objext)): New targets.
* config/rs6000/sysv4.h (SUBTARGET_OVERRIDE_OPTIONS): Recognize
"netbsd' as a V4 ABI.
(ASM_SPEC): Check for -mcall-netbsd.
(CC1_SPEC, CC1_SPEC, LINK_START_SPEC, LINK_OS_SPEC): Ditto.
(CPP_ENDIAN_SPEC, CPP_SPEC, STARTFILE_SPEC): Ditto.
(LIB_SPEC, ENDFILE_SPEC): Ditto.
(LIB_NETBSD_SPEC, STARTFILE_NETBSD_SPEC): Define.
(ENDFILE_NETBSD_SPEC, LINK_START_NETBSD_SPEC): Define.
(LINK_OS_NETBSD_SPEC, CPP_OS_NETBSD_SPEC): Define.
(SUBTARGET_EXTRA_SPECS): Add NetBSD specs.
