GNU Make's escaping rules won't help you there (see
http://www.cmcrossroads.com/content/view/8442/120/) but you can just
define a variable to contain the equals sign and use it to hide the =
from the parser.

e.g.

e := =

abc+$e.cc: ; @echo Making $@

Or if you really want to do something wild you can define a variable
called = which expands to =

e := =
$e := =

abc+$=def: ; @echo Making $@
