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.
