I paid most attention to the later dates in the original email (end of
year and end of next March) and was caught a bit off guard by this
when it was recently mentioned on IRC. Thus I wanted to refresh this
topic on the list, and remind everyone that this is imminent - soon a
default `make universe` without external toolchain will not include
GCC 4.2.1 archs (mips, powerpc, sparc64).

Warner's patch is in progress in review D21942.
