Since oe_runmake wrapper doesn't by default involve PARALLEL_MAKE
outside do_compile() nor PARALLEL_MAKEINST outside do_install(),
enable parallellized make by default when oe_runmake is invoked from
do_compile_ptest() or do_install_ptest() by declaring wrapper task
specific EXTRA_OEMAKE overrides in fashion similar to do_compile and
do_install overrides in meta/conf/bitbake.conf.
Parallel make can still be disabled by resetting bbclass specific
PTEST_PARALLEL_MAKE and PTEST_PARALLEL_MAKEINST variables in recipe
e.g. if a race issue needs to be avoided without modifying source code.
Tested by issuing following command sequence on a 32-core build host:
$ bitbake -c clean util-linux && bitbake --skip-setscene -c compile
util-linux && time bitbake --skip-setscene -c compile_ptest_base util-linux
and found that before this change the result was
real 0m34.684s
user 0m0.753s
sys 0m0.131s
and after this change
real 0m9.868s
user 0m0.749s
sys 0m0.150s
