In order for me to get cross-gcc to build I need to create a symlink
from libpthread.so.0 to libpthread.so. Is that a bug in glibc or is this
intended?

It is intended. glibc 2.34 and later only have an empty libpthread.a,
to make -lpthread (and -pthread) work. libpthread.so.0 is only needed
for running old applications that still link against it; it is pretty
much empty as well (except for symbol version information).
Thanks,
Florian

Thanks for your reply. I'll just create that symlink until a new GCC
release is out, then.

I don't think your issue is going to go away with a GCC update. GCC
just uses -lpthread and does not mind if it is libpthread.a or
libpthread.so. There must be something else in your environment that
causes this.
Thanks,
Florian

You are right. The libpthread.a doesn't exist in this environment.
