Why does Mk/Uses/compiler.mk have code for "# clang not always supported on Tier-2" these days?

Mk/Uses/compiler.mk has the .if test :

.    if (defined(FAVORITE_COMPILER) && ${FAVORITE_COMPILER} == gcc) || (${ARCH} != amd64 && ${ARCH} != i386) # clang not always supported on Tier-2

Should it instead allow clang generally these days via
instead being:

.    if (defined(FAVORITE_COMPILER) && ${FAVORITE_COMPILER} == gcc)


Would this need some sort of exp-run sequence?
