From: Zhang Qiang <qiang.zh...@windriver.com>
When compiling xilinx-zynq board linux-kernel-dev(v5.8) if
"GCC_PLUGINS=y", The following error will appear:
"HOSTCXX -fPIC scripts/gcc-plugins/arm_ssp_per_task_plugin.o
fatal error: gmp.h: No such file or directory"
the GCC_PLUGINS depend on return result of gcc-plugin.sh execution
however in gcc-plugin.sh use HOSTCC to detect the feature of GNU
extension of gcc, this will result that HOSTCC can compile the file
successfully, but HOSTCXX is used in the actual compilation process.
