Describe the bug

1. 编译链接代码后，会生成test目录下生成一个应用程序：utestcases.elf，将其拷贝到sdcard或者编译进文件系统。
2. 测试执行，进入应用程序所在目录，然后执行命令：utestcases.elf all
   3.测试libc，部分case失败；
   4.代码：maix3/software/userapps/testcases/test
   5.失败case：
   utest.pingpong_test.pingpong_timeout_tc
   utest.libc_test.file.fcntl
   utest.libc_test.file.fscanf
   utest.libc_test.math.powf

fscanf的问题是报的这个错吗,需要创建一个可写的sdcard目录。测试代码创建了文件："char *temp_file = "/sdcard/temp_file_fscanf";"

msh />fscanf.elf
msh />fopen tmpfile failed
fscanf.c:65: !!(f=writetemp("      42")) failed (failed to make temp file)
fopen tmpfile failed
fscanf.c:76: !!(f=writetemp("[abc123]....x")) failed (failed to make temp file)
fopen tmpfile failed
fscanf.c:90: !!(f=writetemp("0x1p 12")) failed (failed to make temp file)
fopen tmpfile failed
fscanf.c:114: !!(f=writetemp("0x.1p4    012")) failed (failed to make temp file)
fopen tmpfile failed
fscanf.c:127: !!(f=writetemp("0xx")) failed (failed to make temp file)

utest.libc_test.file.fscanf, 问题已经解决；
