(Warning that I've not tried the below.) It appears that one can back out the -mlong-calls additions and get back to something that builds and installs without needing any cross builds from a different type of host. Going the other way: If one already has clang/clang++ 3.7.1 one does not need WITH_CLANG_BOOTSTRAP= involved as the existing system clang/clang++ can already do the compiles. So try an explicit WITHOUT_CLANG_BOOTSTRAP= to avoiding having a version built that ends up linked with /usr/lib/crti.o (that is not based on -mlong-calls yet) but mixed that with having the -mlong-calls in place for the non-bootstrap clang build to use. The above might be a workaround sufficient for bootstrapping into a -mlong-calls based environment when the arm itself is to build clang and/or lldb. === Mark Millard markmi at dsl-only.nethelp
