armv7: mark EABI compatibility symbols as used

Browse source 
These symbols are not used anywhere in our C code, so
when using GCC's link time optimization feature they
will be dropped even though they're needed by libgcc.
Hence we need to mark them as used so GCC does not stumble
and fall over its own guts.

BUG=none
BRANCH=none
TEST=boot tested on pit.
