yinshengkai 0413d74f31 libs: add gcov framework support
In devices without storage media, you can export data to the
command line and then generate the corresponding gcda file

It can save the result output by calling __gcov_info_to_gcda
The usage is similar to:
https://gcc.gnu.org/onlinedocs/gcc/Freestanding-Environments.html#Profiling-and-Test-Coverage-in-Freestanding-Environments

Usage:
 ./tools/configure.sh qemu-armv7a:nsh
Modify the configuration
+CONFIG_COVERAGE_ALL=y
+CONFIG_COVERAGE_MINI=y
+CONFIG_SYSTEM_GCOV=y
Run:
qemu-system-arm -cpu cortex-a7 -nographic -smp 4 \
     -machine virt,virtualization=off,gic-version=2 \
     -net none -chardev stdio,id=con,mux=on -serial chardev:con \
     -mon chardev=con,mode=readline -kernel ./nuttx/nuttx -semihosting -s | tee gcov.txt
./nuttx/tools/gcov_convert.py -i ./gcov.txt
./nuttx/tools/gcov.sh -t arm-none-eabi-gcov
