-# Multilib notes:
-# 1. ABI_* flags control ABIs libclang* is built for only.
-# 2. clang is always capable of compiling code for all ABIs for enabled
-# target. However, you will need appropriate crt* files (installed
-# e.g. by sys-devel/gcc and sys-libs/glibc).
-# 3. ${CHOST}-clang wrappers are always installed for all ABIs included
-# in the current profile (i.e. alike supported by sys-devel/gcc).
-#
-# Therefore: use sys-devel/clang[${MULTILIB_USEDEP}] only if you need
-# multilib clang* libraries (not runtime, not wrappers).
