[OE-core] [PATCH 1/3] base.bbclass: check all entries of FILESPATH for MACHINE overrides

[Joshua Lock]

The logic which looks for MACHINE overrides in SRC_URI and updates
PACKAGE_ARCH was checking only certain subdirectories of the recipes parent
which, amongst other issues, doesn't account for SRC_URI overrides in layers.

This patch changes the logic such that all FILESPATH entries are checked
for children named for MACHINE.
