This is the dynamic linker/loader.  It is provided by the GNU C library.
The best approach is to avoid this problem and build the programme from
source.

Any other approach is really just a hack.  Possible hacks are:

1. symlink the dynamic linker/loader from glibc to the expected
location.

2. use “patchelf” to replace the reference to the linker on an FHS
system with a reference to the linker from our glibc.

This would only be the first step.  Binaries built and linked elsewhere
are probably also going to have problems finding libraries.  Here you
would have to mess with LD_LIBRARY_PATH to satisfy these requirements.
I suggest not going down this road and packaging the software instead.

Since we don’t support the execution of pre-built binaries on Guix I’m
closing the bug report, but I hope my comments have been helpful in your
case.
