-maltivec does not imply -mabi=altivec, which is intended.
The Bugzilla PR says the target is powerpc64-linux, which
implicitly should enable -mabi=altivec. If this is some other target,
then the BOOT_CFLAGS should include -mabi=altivec. Either something is
wrong with GCC enabling ALTIVEC_ABI or this is cockpit error in the
options used to bootstrap GCC that has been hidden until now.
