# Two multilib layouts exist for now:
# 1) one level libdirs, (32bit) "lib" and (64bit) "lib64"
# these are chosen by us to closely resemble other arches
# 2) two level libdirs, "lib64/lp64d" "lib64/lp64" "lib32/ilp32d" ...
# this is the glibc/gcc default
# Unfortunately, the default has only one fallback, which is "lib"
# for both 32bit and 64bit. So things do not break in 1), we need
# to provide compatibility symlinks...
# This function has exactly two parameters:
# - the default libdir, to determine if 1) or 2) applies
# - the location of the symlink (which points to ".")
# Note: we call this only in the ${SYMLINK_LIB} = no codepath, since
# there never was a ${SYMLINK_LIB} = yes riscv profile.
