make: Detect assignements in MAKEFLAGS

The format used in MAKEFLAGS can follow 2 different formats. In the first
case it accepts flags without the leading - and without spaces, and in the
second case it accepts flags with leading - and with spaces. Only in the
second case assignements are supported.
