The errors don't make much sense. Are you sure that system libs in lib64 aren't 32-bit somehow?

Does something like this clarify?

$ file /usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../lib64/crti.o
/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../lib64/crti.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

$ file /usr/lib64/libpython2.7.so
/usr/lib64/libpython2.7.so: symbolic link to libpython2.7.so.1.0

$ file /usr/lib64/libpython2.7.so.1.0 
/usr/lib64/libpython2.7.so.1.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

Probably some bug in clang/lld then. I'll try debugging when I get home.

It looks like "-L/usr/lib" breaks the link command, see for example:
