The fact that it replaces $ORIGIN by the current directory when /proc is
not mounted is one part of the issue. It has already been tracked and
fixed in #884615.

This is the second part of the issue. The dynamic loader has no way to
find the location of the binary without a mounted /proc, that's why it
fails to find the GHC libraries.


Retitling / tagging the bug accordingly.

The problem you encounter is due to the use of GCC 11. glibc headers
need to be adapted for that. This has been done upstream in glibc 2.33,
which is already available in experimental. It should arrive soon in
sid. Using GCC 10 is another alternative.

Aurelien
