I traced this problem to the recent gcc import and then ran out of
time to debug further.  Glad that you've got furter than I did.

It seems that strcasemp is defined in the repl binary:
08061abb T strcasecmp
         U strcat_at__at_FBSD_1.0
         U strchr_at__at_FBSD_1.0
         U strcmp_at__at_FBSD_1.0
         U strcpy_at__at_FBSD_1.0
         U strdup_at__at_FBSD_1.0
         U strerror_at__at_FBSD_1.0

So I'm really not sure why the linker is choosing libc's version
over this one.
