[OE-core] [rocko][PATCH] module-base.bbclass: fix out-of-tree module builds with custom EXTRA_OEMAKE

[Denys Dmytriyenko]

From: Denys Dmytriyenko <denys at ti.com>

Commit d2aa88a6a92985f21414fceea2dc0facbf7f8779 was meant to backport build
dependencies on bc-native and openssl-native, but it also changed execution
of do_make_scripts() from calling make directly to using oe_runmake. That
change was made in master/sumo as part of a separate make-mod-scripts recipe.

Unfortunately, that doesn't work here in rocko in the context of module-base
class, as it gets executed inside out-of-tree module environment. Quite often
those out-of-tree modules provide own Makefile with custom EXTRA_OEMAKE var
defined. But do_make_scripts() gets executed within STAGING_KERNEL_DIR and
cannot simply use custom EXTRA_OEMAKE set by a module.

Move back to calling make and passing HOSTCC/HOSTCPP directly w/o using
EXTRA_OEMAKE.
