selftests/powerpc: Pass make context to children

Make supports passing the 'jobserver' (parallel make support) to child
invocations of make when either
	1. The target command uses $(MAKE) directly
	2. The command starts with '+'

This context is not passed through expansions that result in $(MAKE), so
the macros used in several places fail to pass on the jobserver context.
Warnings are also raised by the child mentioning this.

Prepend macros lines that invoke $(MAKE) with '+' to allow passing the
jobserver context to these children.
