collect2: error: ld returned 1 exit status
These symbols are present in the src/debug/.libs library, because it's built
without optimization so there are additional template instantiations that
aren't inlined away.
The conflicts are all due to "std::enable_if" in a return type matching the
pattern std::e[a-q]* (line 83).
This is probably wrong on all targets, but the linker only gives an error on
Solaris.
