Stefano Stabellini July 9, 2014, 8:34 p.m. UTC 
rules.mak adds cflags specific to the target source file ($($@-cflags))
for last on the compiler command line.

As a consequence when compiling arm-a64.o, g++ might end up picking the
wrong utils.h header file, because it looks for utils.h on all the other
include paths first.

Fix the issue by passing the source file specific cflags first.
Do it consisently for *.c, *.cc, etc.
