commit 1c8cafe293c6b905543f8fe7971256d429d2f494 Author: Marc Jones marc.jones@se-eng.com Date: Thu Nov 6 15:50:22 2014 -0700
build: Add ccopts back into the build
The ccopts mechanism is needed for passing ARM assembler flags to GCC. There are many gotchas in adding ASFLAGS. As things have moved around, the revert doesn't remove cleanly, so this reverts and cleans up the ccopts.
This reverts commit 25b56c3af514faa8a730d56fe14cae4960ac83aa.
