我刚刚更新了android sdk，现在我在尝试运行adb时遇到“找不到文件”。
奇怪的是，文件就在那里。路径或文件中的任何位置都没有符号链接。
$ ltrace /home/gcb/Android/Sdk/platform-tools/adb
Can't execute `/home/gcb/Android/Sdk/platform-tools/adb': No such file or directory
failed to initialize process 30073: No such file or directory
couldn't open program '/home/gcb/Android/Sdk/platform-tools/adb': No such file or directory
$ pwd -P
/home/gcb/Android/Sdk/platform-tools
(here i check every single step with `ls -la` and confirm nothing is a symlink)
$ ls -lah adb
-rwxr-xr-x 1 gcb gcb 1.2M Sep 6 13:55 adb
$ file adb

$ ./adb

$ /home/gcb/Android/Sdk/platform-tools/adb (auto-completes fine with tab)
