make: *** [default] Error 2

on upgrading dosemu inoperable compile flags are thrown together resulting in the build to fail.

Reproducible: Always
Steps to Reproduce:
1. Install dosemu-1.2.0
2. Upgrade dosemu

Actual Results:  
compile failed

Expected Results:  
compiled and ran

Created an attachment (id=58004) [edit]
patch to unset KERNEL

Unsetting the KERNEL environment variable solved the problem for me.

*** Bug 91434 has been marked as a duplicate of this bug. ***

2 more machines affected by this.

Created an attachment (id=58573) [edit]
comment out KERNEL in Makefile

This is probably a better patch, as that KERNEL variable is not used at all
anywhere in dosemu, and unsetting in the ebuild is generally a bad idea.

plz fix - because 1.2.0 and 1.2.2-r1 are stable on x86

fixed
