It should be possible to tell Perl to suppress its Unicode handling. Try
adding this to the build, either to some appropriate CONFIG_SITE* file,
or (my preference) to the Makefile that builds the problematic source files:

    # Sources here use a non-UTF-8 encoding
    PERL = perl -C0

Our default -CSD setting tells Perl that all I/O streams should be
assumed to use UTF-8 encoding; -C0 says no I/O streams use UTF-8. I
would like the EPICS default to continue to use UTF-8 if possible.
