Solution
In several customer instances, $ORACLE_HOME/lib32/ldflags was a symbolic link that pointed to a location that did not exist. This was resolved by performing the following UNIX commands to point the $ORACLE_HOME/lib32/ldflags to the $ORACLE_HOME/lib/ldflags :
$ cd $ORACLE_HOME/lib32
$ rm ldflags
$ ln -s $ORACLE_HOME/lib/ldflags ldflags
Then, stop the web tier services (adopmnctl.sh stop) and relink the forms executable(s):
$ cd $ORACLE_HOME/forms/lib32/ $ make -f ins_forms.mk install
