Did I miss something about building a static IOC? Having to mess around
in the epics-base files doesn't seem ideal... To cover all my bases, I
also tried doing this on epics-base 7.0.7, which required the same steps
to spit out a static executable.

The developers of glibc try to discourage completely static linking
as some parts of libc.so will implicitly try to load plugin libraries
for things like user account database and hostname lookup.  There are
also some hardcoded paths which distro libraries may have changed.

Of course, there are some cases where this may not practically be
avoided.  Such as you describe where (I assume) you don't have
access to the toolchain which was used to build the system libraries.

In such a case I guess you will have to hope for the best!
