There is another gotcha-issue with the change from --no-threads to --threads=1 based on neither working for both 10.0.x and 11.0.y: which ever one is listed in /etc/make.conf (say) will be wrong for other one of: A) building the bootstrap toolchain B) using the bootstrap toolchain The LDFLAGS.lld definition would need to be conditional on the distinction in order to be correct inside each type of context. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
