toolchain.eclass: drop unused --enable-altivec
--enable-altivec does not do anything since gcc-4: https://gcc.gnu.org/legacy-ml/gcc/2005-03/msg01091.html The change drops passing of --enable-altivec for all gcc versions and drops IUSE=altivec for gcc-10+. Once gcc-10 is stable everywhere we can drop IUSE=altivec for all gcc versions. Reported-by: Georgy Yakovlev Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
