This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into
account (if set), so that packages do not need to manually override
PKG_BUILD_DIR just to handle variants.
This also updates most base packages with variants to use the updated
default PKG_BUILD_DIR.

(cherry picked from commit e545fac8d9)
Due to limitations in the symvers treatment and the mei drivers
exporting the same funtions, modpost might use the wrong mei driver
to link against.
Work around this by renaming them all to the same name, making it
always the "right" module name even if the wrong file was used.
