I created a pull request for the patch at
https://github.com/krb5/krb5/pull/1111 .
There are a couple of things I am unclear on:
* On my systems, "pkg-config --libs com_err" displays "-lcom_err". If I
add "--static", "-lpthreads" is also displayed. I don't know where the
librt dependency is needed.
* In the pkg.m4 modules we use, there is a PKG_CHECK_MODULES_STATIC
macro, but we don't currently use it, and nothing else seems to add
--static to the pkg-config options. In your environment, does
"pkg-config --libs com_err" display library dependencies even without
the --static option?
