Ok.
Though wonder if for the TARGET_LIBC_PROVIDES_SSP case LINK_SSP_SPEC
shouldn't be
#define LINK_SSP_SPEC "{fstack-protector|fstack-protector-strong|fstack-protector-explicit|fstack-protector-all:}"
and
gcc/config/freebsd.h:
#define LINK_SSP_SPEC "%{fstack-protector|fstack-protector-all:-lssp_nonshared}"
should be changed too (adding both -string and -explicit).
