WSL2编译android12之You are building on a machine with 15GB of RAM解决

1.报错如下

15:55:08 ************************************************************
15:55:08 You are building on a machine with 15GB of RAM
15:55:08
15:55:08 The minimum required amount of free memory is around 16GB,
15:55:08 and even with that, some configurations may not work.
15:55:08
15:55:08 If you run into segfaults or other errors, try reducing your
15:55:08 -j value.
15:55:08 ************************************************************

2.解决
