feat(fake_host): Enable generating profile data
This patch adds necessary CFlags for generating the profiling
data when binary is executed. A grof file `gmon.out` is generated
when the fake_host binary is executed and it can be processed
using the gprof tool. A sample gprof cmd is shown below:
> gprof build/Debug/rmm.elf > prof.txt
The `fomit-frame-pointer` was not compatible with profiling options
hence this patch moves the option to make it AArch64 specific.
Also `-gdwarf-4` option is made common for fake_host and
AArch64.
