You need supp_cd to be first in an index.  Try

Looks like that does not work. BTW this does work (without adding a 
separate index) in postgres.

mysql> alter table hpi_supp_agmt add index i1hpisuppagmt (supp_cd);

Query OK, 28635 rows affected (4.89 sec)

Records: 28635  Duplicates: 0  Warnings: 0
OK, now table hpi_supp_agmt has supp_cd first in the i1hpisuppagmt 
index, and table supp has supp_cd first in the p1supp primary key index, 
so supp_cd should now be a foreign key candidate.

mysql> alter table hpi_supp_agmt  add constraint f1hpisuppagmt foreign 
key (hpi_no) references hpi;

ERROR 1005 (HY000): Can't create table './gem/#sql-c3f_2.frm' (errno: 150)
But here you try to add a foreign key constraint using hpi_no, which is 
not first in any index.  And what is hpi?  Did you try your original 
statement?

alter table hpi_supp_agmt add constraint foreign key (supp_cd)
references supp(supp_cd);
I would expect this to work now.  At least, it does for me.
