So, anyone probing for dlopen() finds it in libfakechroot.
However, when that dlopen() is called you get a (very confusing)
link error. This is a bug because if the underlying C library does
not have dlopen() then libfakechroot should either not export it or
should forward calls to the

Yes, it allows the build to continue successfully. Specifically it
allows the libgcc_s.so to be built.

How does LTO need dlopen? It seems it only cannot use the linker
