The actual problem are not the runtime libraries, which already know to
search $builddir/.../libgcc for unwind.h and related files. The
copyback is only for the benefit of the testsuite (gcc.target, g++.dg,
gnat.dg, and gcc.dg) where I was too lazy to deal with changing (or even
setting ) the include paths, but took the easy way out since gcc/include
is in the include path by default.
