rockbox/firmware/target/arm/support-arm.S, branch master

Move supprt-arm.S to separate library.

2012-01-21T17:39:19+00:00

Core, codecs and plugins link it separately so this gets rid of SOURCES trickery.
Don't build it for hosted targets.

Change-Id: If15ef90e93cd218a4352ae8e89eea95d3122452f

Fix assembler .size directives. Currently used binutils don't complain, but 2.21.1 treats these as errors.
