error in invoking target 'agent nmhs' of makefile

I come across a situation that servers & Operating systems are (O/S) are getting upgraded and we cannot perform in place upgrade for easy roll backing capability.

Also new O/S does not support the Database version.

We need to restore the Oracle database into unsupported Server version. We have copied the Database binaries and during the Database upgrade we got below error.

error in invoking target 'agent nmhs' of makefile

Workaround:
During upgrade or clone  you will get this error when relink is running

Here is the workaround 
ls $ORACLE_HOME/sysman/lib/ins_emagent.mk

Search for the line 
$(MK_EMAGENT_NMECTL)
Change it to:
$(MK_EMAGENT_NMECTL) -lnnz11

Goto Database upgrade window and click on "Retry" and upgrade should run successfully.
