Thank you.

Does --disable-libstdcxx stop building libstdc++*.dylib?

For info, that list of targets is longer than most of us would need! I
included Fortran because I was developing my gnat-math-extn project on
Sourceforge, and Objective C[++] on request.

Also, the configure flag --with-boot-ldflags supports relocation of the
built binary, and (together with the patch gcc-6.1.0.diff), suppresses
GCC PR 61027.
